Ok so when Al and I first went to SES 3 years ago, we didn't know too many people. We also felt a little left out in so many ways, but once we put overselves out there to meet people and to ask others to ride with us, we found everyone was receptive. It's also a great way to pick up a plethora of knowledge on how to become a better rider.
I was extremely intimidated at the first session because I had been on plates for 3 months before going to Aspen and after watching so many carvers ride (let alone female carvers), I was like "I'm just a punkass on a snowboard"! but that didn't stop me from trying to ride better and from getting to know others. Now at year 3, I know so many of the those wonderful carvers and have met many more in the process and it was because I wasn't afraid to approach or to be approached. I still have a lot to learn and will always be open to advice whether it is about my equipment, riding style...whatever.
My advice is to don't be afraid to introduce yourself or to ask people to ride with you. Also coming onto BOL is another great way to cement relationships even before SES or any other session for that matter, it's always good to chime in on a thread with experiences, jokes or whatever else you can think of. I promise we don't bite.....!
