I'm finding I have the same problem right now. I've just put my downhill mountain bike on the market, because I used it one day last year, and I'm not likely to use it any more this year. I still have the all mountain bike so I'm not without wheels if I want to go and ride, but since getting a decent motorcycle, that's become the toy of choice for sunny days. Being able to jump on that and just go beats the hell out of rounding up all my gear, getting up early, strapping on the MTB and driving for two hours plus to get to the bike park, or at least 45 mins to get to the local downhill spot (and hoping that I can find a shuttle lift once I get there). I do enough of that in the winter, I'm kind of over doing it in the summer as well. I do love it, when I make the effort, but it's just making that effort sometimes ...
I couldn't agree more. Life moves along, and all. Doing new things gives you new opportunities to discover the next thing you love.
