It was really muddy

Luke can barely keep his bike from getting bogged down in the ruts.
Austin has no trouble zipping along. He wiped out later in the day.
I was getting a little cocky in the mud holes, and one got the better of me.

This was a common occurrence, one kid stopping in the middle of the trail to see if I was "ok" and becasue their concern for me I ended up wreaking a lot more than I would have if they didn't keep stopping to check on me. (it was sweet of them)
