One thing I always regretted was that during the construction of Martin's Station in 2002, I could have gone there for a week and participated in the building of the fort. I didn't. I thought that since I had no experience in this, I wouldn't be of much help. Turns out that a lot of others were in the same situation as me, but they went anyway. I should have gone!
