As with most things the only thing I have control over is myself. I live in an HOA. Don't get me started but the house was PERFECT. Anyway the wife and I shut off all our lights when we hit the sack. Internal and external. When I get up to take my dogs out I swear it's like what I imagine an internment prison camp is like at 2am. The neighbors each have several bright as heck lights on on the back of their homes. I mean disturbingly bright. I've thought about asking the HOA to put something in the news letter about please turn off all external lights after 10pm or some such. But I don't think anyone would care. Sigh.
I can just never get over how absurdly lit up everyone's porch and back of the house is. This is not a high crime or any crime area. But it's lit up like a prison yard. Yeah this wasn't a very constructive post but i needed to vent about this. Sorry folks.

Just let them?

Found out I need to travel 400-500 kilometers for hitting a grey area, mixed a nearer one up with dark blue. So it will maybe remain a distant dream?

Borderline yellow will mostly have to be good enough, need to have access every time it's clear weather. Approximately Bortle 5.5 would be my thing. I know people are observing with worse.

I have some hopes for the northeast area from a spot I will check out during the weekend, could be pretty dark in that direction...

Ha yes, they are. I'm always amused by the folks observing from inner cities (and I admire their dedication, too). But, they also surprise me with what they can see, and it's a little humbling to read about when I've just come in from a frustrating night of trying to see something more than a faint smudge in some faint DSO, since I realize I actually have it a lot better than some.

I've startedusing theDark Site Finder with thesatellite mode checked for combining light pollution with ground view, found the latter today. You can even dim the color for seeingthe ground better, look in the right upper corner!Earlier have used the Light Pollution Map for the ground view. So I'm hunting optimal places for each of the light pollution grades. Realized I can reach even dark green at the shore without driving much over an hour. Light blueand especially the dark version are almost totally out of the question for a one day trip. The grey areas are definitively so, even the lighter version. But think I could make a project out of visiting each area when thecircumstancesare optimal. Think I've already found my routine observation sites, they go from orange to yellow. You can't make your regular observing a pain, or you will not be going.

It's television. There may be zero crime within a hundred miles, but if there's crime on television, and people sit in front of the television for hours ata time, that's their reality. Explains a lot these days.

Around here, sea turtles get protected from light pollution. Humans are left to shift for themselves.

The latest thing on TV is "tactical flashlights." My nosy neighbor seems to have one. Don't get me started.

I don't blame you at all for wanting to vent.

I find the darksitefinder pretty accurate - the lightpollutionmap is good at finding much more precise points of light (like little villages) - but not so much on the existence of light domes. And I'll just add: getting to a dark site is still possible for most people. Unless you live in NYC/philly/DC/Boston corridor, you are within driving distance to a dark green site - which is darn good. Still plenty of opportunities to enjoy the hobby if you are dedicated. Not as easy as it once was - but still perfectly possible.

Getting TO a "dark" site is still possible if you have reliable transportation.

Setting up AT a "dark" site is a whole'nuther thing.

No idea what you mean. I have no issue setting up. Sometimes I have an issue with uneven ground or mud or bugs, but I work around it.

Then you must have permission to use, or ownership of, your observing site(s).

I have three. Two are state preserves / wildlife management areas - and the third is a farm. I literally asked one guy if I could set up from time to time, and he said yes sure as long as I let him take a look. I highly suspect that anyone who can't find a farm to set up on simply has not asked. I can't see it taking more than 3 people before you get a yes.

The best is to combine the two. Darksite finder gives general zones, but there are of course variations within and LPI can help in finding the best spot.

Also, you can turn on SQM layer at the LPI and often figure out where the good dark spots and hangouts are. Try it!
