After Linda’s post yesterday I just had to add my own 2 cents about gator bags. I use ’em and I like ’em. But, that said, I never allow gator bags to sit against trees for an extended period of time (Maybe 6 weeks when the tree first goes in). That’s just asking for trouble!

What I Learned This Summer (Part 1)
Just flew in from St. Louis and boy are my arms tired! [Baadum – ch!]
