I will be walking in the 3 Day walk, this year. I will be walking in Arizona (taking a few days to check it out, also). It is a 60 mile walk over 3 days. Pretty awesome and intense!
I did it in Chicago in 2005! Was a most significant walk for me...although I told people I could do it, was not sure I would make the WHOLE walk! I did, I rock :D! Very little confidence problem here ;D!
