WOW!!!! Bears will try to get into anything!!
My Dh call's Duct Tape "100 Mile an Hour Tape"
He's a pilot, and says it's good up to 100 miles an hour.
I once patched together an old rusted car we had, sprayed over the duct tape with white rustoleum paint and even sold the car for more than we paid for it after driving it for 5 mos. (this was in Okinawa when DH was there on a deployment back in 1986)
