Most of my buddies I met through cycling, however most are skiers.
I do have a rule that if I plan on going, I go no matter what, even if everyone flakes. Sometimes it's nice to go at your own pace, and enjoy the scenery,etc.
I prefer to ride solo in all honesty. I can get way more runs in, do the runs I want to do, ride when I want to ride, and hardly any wait time in lift lines riding solo. Sometimes it's fun to go with a group if I want to take it easy that day, but spending two hours running late waiting for everyone to get ready and meet up then another two hours at the lodge getting something to eat and drink isn't exactly my idea of a fun day boarding. I just listen to my ipod on the lifts unless someone wants to chat. Sharing a lift with strangers has its ups and downs, one time a skier was talking to me how retarded snow boarders look and are and asked if I felt the same way, I lifted up my leg and showed him my board and he went beat red.
