I know exactly how you feel! The guys are right. Wait until you get there and wow, after you get back to the default world. Last year was my first at age 75 and it was truly a peak experience of my life. No doubt it will the same for you. Just remember to leave your inhibitions at home.
I think about getting back on the Playa every day and plan for it all the time. What fun, what irresponsibility, what caring, what creativity!
By the way, I'll probably be camping in Hushville, look me up.
