I've had something similar happen to me. I was stung by a jelly fish, poured rum over the sting and then rubbed courtazone cream on it. Fixed me right up.
I have yet to catch a Tarpon also, Boca Grand pass is the place to go on the West Coast, Government Cut in Miami is also very good. I hooked up with one that was close to 200lbs, but I was using snook gear so i didn't stand a chance. I'm not to sure how he can go out on Superior and not the Gulf. I would rather be on the Ocean in rough water that a freezing cold Lake!
