I was in that race. I'm pretty sure I was the one that yelled if you were with us or not. It was pretty frustrating all the people we lapped. There were probably about 10 groups of 2-5 riders that we kept lapping, but then they'd hop on the back of us, and then attack of the front. It was pretty hard to tell who was with us or not.
It was a good race though, no crashes. I sprinted with one of the porcupine guys and got 1st.
As far as clipping into Keos: I like that they're not double sided so the pedal is always in the same position. To clip in I just put my toe just above the spindle from the back, then just slowly drag it forward and it'll pull the cleat to horizontal and then clip.
