You should give yourself a break, it was a very hard map. And we don't get many chances to practice on such hard maps. Also, you can think about how you will handle such terrain in the future. Maybe going slower and reading every feature? Or taking safer routes on trails? Or something else? Glad to hear you're not too discouraged, and we'll see you in the woods again.
Thank you for your encouragement. I agree with the part about the trail--that was my mistake at the US Champs on the second day. I got myself into some really difficult terrain where I couldn't see.
On the day I got lost, I'm not sure there was a good trail, but I know how I could have done much better. I still don't understand how I got lost. I knew the safety bearing was NE and tried to go that way. The funniest part was that I heard a bunch of people talking and smelled food cooking and crashed a condominium get together. I asked them which direction to go for the hospital complex, and I think they steered me wrong.
Anyway, orienteering is just too much fun for me to give up.
