I have never heard of the 5 gallon bucket idea until tonight. DH returned home form his civil war re-enactment at Antietam, MD and told me about it. Then I find it on here. WOW! The other week one of those critters was on my computer desk twice. I moved the tower slightly and the next time that mouse ran along the tower he ran out of space. Needless to say when he ran off the edge, I had the trash can waiting for him to jump into. It was nice of it to acomodate me that way. Now where did I put that bucket.
