oh Deb, be careful. Sounds scary! I hate walking on ledges!
I also hate deep knee bends!
I myself am very nervous about the Menage a Trois race i am in on Sunday.
my racehorse/captain is WAY competitive. I must be nuts!!! my poor DH is having anxiety dreams about this same race. He is on a team with another big strong character and a very sensible but fairly fast woman. I am the only
one on the back of a tandem (that i know of)
