Man... I miss the days when I looked forward to riding. My car has been laid up for about 8 months now, So I have been relying on my bike to get me to and from work every single day, rain or shine, for the entire spring/summer. This sort of riding definitly kills the fun of riding for me. Luckily, I am about to start putting the car back together, and it will be sold within a month, so I can get another car and stop riding the bike all the time. Give it about a month and Ill be up for some 12 hr riding days on the weekends again.
As for riding with the group... I would have to say Im out. It seems that all of the rides you organize are at night, and I never really liked night riding. I always seem to be too short on light in front of the bike. Try one during the day, preferably on the weekend, and Ill be in.
