Yoo Hoo! Any intelligent life left in there?

At 7 this morning I ran to/from and with the Boulder Road Runners, including a 2 minute/4 min/6 min/4 min/2 min ladder followed by a set of strides. At 6 this evening I ran to Boot Camp of the Rockies and did 40 minutes of hill repeats (not counting the ~3 miles of uphill/downhill to/from BCOR). One might now reasonably ask whether there are any active brain cells in this body (and, if so, are they being used). While you ponder that question, I believe I'll go put my feet up...
