The Bike Hermit has Posion Ivy

[Owlie]

I'm assuming the canvas is either coated or waxed and that's why the caution about what to use on them?

I'll never forget the PI I had on my wrists when I did Women's Quest. The week before I'd been clearing brush that included both PI and multiflora rose. My glove gauntlets were a little too short and the only thing I can figure is that I must've got PI inside the rose scratches, so it was under the skin. By the end of it I had four layers of blisters under blisters under blisters under blisters, the lot of it oozing like some disgusting science fictional creature. Thank goodness it was only a few square inches on each wrist, because the itching nearly drove me out of my mind as it was. Not much sleep for a couple of weeks!

Ugh!
