I have seen the number of people that I can ride with dwindle so I ride alone most of the time... I think its tough in this area, even people I know that skied or rode all the time seem be the single trip a year sorts now.
Most of my riding with others is on trips so I typically enjoy it... although it does slow me down. I have also done a solo trip in the past when traveling for work.
I am possibly going to do that again.. stopping in SLC on my way home from LA at the and of the month. In LA on the 29th and trying to leave Thursday the 31st to get in a "weekday" of riding Friday. Anyone around during that time interested in riding PM me. I'm good for treating for a few beers in exchange for some guiding as it will be my first trip there.
