I just look at it week by week, if it is over 90 degrees during the day, I stay home. I don't have an RV so I don't travel anymore either. It's still fun to compete, despite the hassle of loading and unloading everything by myself. I made it out to 12 races last year, one quarter final and one semi, not much to speak of but still fun.
One thing I have done proactively is to sell off all the parts I had, I kept only a spare transmission. Doing the same with junk in my house, don't want to leave a mess behind for my kids to deal with.
