I equate the drop in email and message board traffic during the Fray to that of foot and automobile traffic during Burning Man. It sure gets quiet on HOWL and the HO sections of Hobby Talk, SCI and other message boards.
I also equate the re-entry into the regular world after the Fray to be like olympic athletes following their performances every 4 years. I once heard Jonny Moseley talk about his life after winning his gold medal in which he wanted to do ANYTHING but go skiing. He had spent every moment of his life for many years working to that point in his life. Having won a gold medal, he put up his skis for a long time before even thinking of hitting the slopes again. I imagine many Fray competitors suffer from T-Jet fatigue after running their 45 year old toy cars for 2, 3 or more days straight, especially after "training" and preparing for the event for weeks and months.
