Our guide was Lester Zook for a wilderness survival one-day course. We hiked a couple miles into the George Washington National Forest on a warm day. Lester focused on Shelter Building (including a very helpful session on knots), Fire Building ( several tips were new to me), and Navigating (basic map and compass work). Lester is so knowledgeable about wilderness survival, you can pepper him with questions and he has clever workarounds for any problems. I would have appreciated learning a little about finding and treating water, but it was a long and rewarding day without adding that. Loved the balance in our group of 12 -- half women, half men, ages 12 to 62, racially diverse, all very friendly, helpful and polite. Can't say enough about how well done this program is.
