USFS (and alikes) safety?

[Acei]

Admittedly, I've never been to a USFS. Is it safe to leave trailers all day long while you visit surrounding places?

The one at Serando lake, right off the Blue Ridge parkway was good never had a concern.

We're newbies that have only camped in a couple forest service campgrounds, but never thought twice about leaving for the day to hike the surrounding parks. Are you thinking about boondocking on forest service lands or camping in USFS campgrounds? We haven't boondocked yet, but are looking forward to it!
