You must be camping in a camp ground that allows you to use your generator anytiime you want to. Seems like every public place we stay at here on the East side of the US all have generator run time restrictions in place which are usually two hours in the morning and mabe three houts in the early evening. No where will they allow the generators to run after 8PM at night...
We have gone to a few Natl Forest areas that allows generators from 8AM to 8PM but never after 8PM...
Seems like only dispersed camping lets you do anything you like. Not many of those places here on the east side...
