The 10 penny variety where it takes several solid strikes to get it flushly driven into a dense piece of hardwood. And that was okay, I guess.
It was an organized 62 miler with 100+ riders and the half life of the group was probably 9-10 miles. By 20 miles we were down to about 20 riders. By 30 miles we had averaged around 24 mph and it was down to 10-12. We started to hit some pretty good hills that made me wish I hadn't done the 50+ miles the day before trading pulls with some of the local tandems. Three or four of us got really nailed on a longish steepish hill and dropped off the group-or rather they rode off without us! At least there were enough riders left to trade pulls for the rest of the ride and we were still able to finish in less than 3 hours for an average around 22 mph.
While I didn't crash I could emphathize with LA seeing riders easing off ahead and unable to do anything about it.
