Hello Old Friend

The other day I was driving down Birchwood and who did I see but, Tippy, the black squirel with a white turft on his tail. He used to frequent my backard but he seems to have migrated to Forrest Hills. I hope he's having fun- there are alot of trees and nuts there. Although I had not seen hin in at least 3 years, does anyone know how long squirels live? He seems like an exeption in the age categogy...
