I'm ssoooooooo allergic to PI that I don't wish to come within miles of the stuff. And of course it's all over the farm. So I stay on the trails, don't wash Ed clothes depending on which direction (E-W - ok, N-S - no) they plant the tobacco field (the dust is what gets you). And I leave the wild raspberries to everyone else. I planted cultivated ones in the garden.
Took me an entire summer working on a creek for the MNR when I was 19 - everyone else got it quick. When it started I had it chin to toes and it missed - nothing!!!!
I admit to being slow, it took 7 yrs (well, 2 that I lived here - but I picked wild ones for 7) for me to plant that raspberry patch.
