Don't take a toothbrush- a twig will do the same thing. Just make sure you know what kind of tree you're using.
Thanks to all. Should have mentioned the Mrs. and I have camped for many years but we stay at modern campgrounds like the KOA in Townsend. You can imagine what we take for 9 days- two adults and a dog. Just a matter of paring down the list to what you can carry in. Did think of a question- where do you park to keep thieves out or do you booby trap it like a 007 car?
I'll look for a time later in the year and put out an invitation for others. The more, the merrier, they say.
