Were there little puffs of dust as you ran on the trails?
No dust. The trails have been well watered and manicured by all the rains over the past week.
While I was running, the last race in the mountain bike race series was going on (part of the reason I was running where I was, to give some encouragement/harassment to some of the folks I knew in the race.) They were *very* lucky that today's rain storm skirted by Happy Jack somehow--a direct hit would have left behind a real mess. I bet the organizers were wondering if they were going to have to cancel the thing as the storm was hitting.
