That's correct, I do live in Northern Virginia. Although I can understand the attraction of an outing with a group, however large or small, it is problematic. For one thing, you have to adjust your comings and goings to the group's schedule. Likewise, you have to adjust your pace to that of the group and I wonder if I'm perhaps a little too old for something like that and might have trouble keeping up. And anyway, I'd rather be able to take any opportunity for nude hiking that comes along. I think I'm too different in so many ways, judging from the people I've passed on some local trails. In any event, I don't get out away from home, meaning more than a few miles from home, nearly as often as I'd like. I'm trying to keep down the mileage since I retired, too. I think a local nudist group managed to do a few nude group hikes somewhere not too far away, which is encouraging.
Once, many years ago, I was getting ready to go on an overnight trip up in Shenandoah National Park, in the northern section, and still in the parking lot making my last minute preparations when first one car, then another and another pulled into the parking lot and a group of about 20 young men and women, all at least 30 years younger than me, got together and set off down the trail. I followed five or ten minutes later and never saw them again. The woods, you might say, will absorb a lot of people. Another time, in the very same spot, I had just returned from an overnight trip, I think in early spring, when a park ranger drove by and said the park was closing because of the weather (freezing rain was just starting) and that I had to leave. He also checked my camping permit while he was there, too.
I've mentioned before somewhere that there are some trails that I feel sure that the chances of meeting another person would be very low but those trails are not the best for hiking.
