Tied up with van issues in the AM, but borrowed the mechanic's truck.
Solid hike up the Caps trail, waited out a potential storm at the summit cafe, then ran the road down to the base, hiked back up half way and ran back down.
We caught a bit of the MTUnicycle XC race too.

Then we discovered that I left the dome light on (need to turn it on to start the truck) and almost nobody carries booster cables in summer (or want to boost a big truck with smelly runners).
Luckily the 20th group or so had cables. Van's fine now.
