Halloween Party: Brooks BBQ, Catch the Ghost Fun Run and Anniversary Sale at Fleet Feet Menlo Park, Menlo Park, CA. Event date: 10/30/10. Time: Varies.

I dropped by Fleet Feet Menlo Park to hear Dean Karnazes speak and a couple of signs in the store indicated some of their upcoming events.

My apologies...  The lighting wasn't very good, and the pic didn't turn out as well as I had hoped.

Events on 10/30/10:

1. Brooks-a-cue  12 Noon to 3 PM
2. Catch the Ghost Family Fun Run  [I believe it's at 3 pm...please confirm with the store at:  (650) 325 - 9432 to avoid disappointment.  Update:  I heard the Ghost is fast and there will be T-shirts passed out to those who tag/touch the Ghost, so I guess it's probably not tortoise-friendly.]
3. Anniversary Sale

If you're in the area, it sounds like a fun event.
