[BR-Crater] [Stratofox Team] Crater Assault 3 at Black Rock next weekend

[Owen DeLong]

I'd love to go, but, I'll be assaulting a much bigger depression in  
the earths
surface this weekend.  I'll be teaching a SCUBA class, so, we'll be  
out in
the Pacific Ocean.

Hopefully I can catch the next one.
