I would suggest a bug out place that is very difficult to find, a place that regular people would not try to get to, this may be a hunters blind on the side of a rock face, a small island on a rural lake, almost any swampland. One of the ideas I like was from a scene of the movie “Red” where a derelick junk car was used to hide a stairwell to a bunker.
With the expanded use of drones from what may be not so friendly forces research into concealed coverings should be done, especially thermal scanning. FLIR can be defeated by very good thick insulation like several layers of blueboard insulfoam with fiberglass batting sandwiched between.
Any heat source like for cooking needs to be carefully set up so as to diffuse away from the campsite or drawn into an underground muffler so to speak such as a steel barrel so it will cool off. Heat will give you away.

I live in town in a place exactly like you wrote above. If you had the address, you couldn’t find it because nunerous people have tried and still miss it. No regular people try to get here because they don’t know it exists. It’s just a strange placement that happened and it’s an optical illusion so that a brain passes by where it is.
I didn’t buy this place because of that, it didn’t cross my mind, in fact it was a bother because I’d have to watch closely to get here myself and I still do or I’d pass it up. So, I think it was a God thing that put me in this spot in town close to everything I need, yet being hidden.
