I started racing in '04, and have raced every season since, with the minimum being two events, and the max being 5 events (last year). I was going to make it six events this year, but then PPIR got cancelled, so it looks like it'll be 4. While racing is the most exhilirating and fun activity I do, it is definitely not my top priority. In a nutshell, the infrequency of my appearance on the grid boils down to $, time, and timing, but for me, this year is no different than any other year.
