Jellyfish Beware!

This Saturday I'm racing in the Flat as a Pancake Staten Island Sprint Tri. I've been looking forward to the race for awhile as a way to help prepare for the NYC TRi. However I just found out that last year a number of racers were stung by jellyfish. I guess the average person might not worry about this but with stuff like this I worry. My allergies are pretty broad and include everything from tomatoes and shellfish to fire ants. I've gone into shock twice from being bitten by fire ants. So the thought of being stung by a jellyfish makes me wonder if this sprint tri is the right thing to do. I emailed my coaches and called the race director. Who does that? Who actually calls the race director? I do! His name is Joe and he couldn't have been nicer. He explained that he moved the race up an entire month because of the jellyfish and the number of people who were stung last year. Turns out late july and early august are jellyfish season in the Atlantic- not june. He assured me that in wet suit I'd be fine, hopefully. Hopefully. I tried to do some research online about jellyfish and exactly when they come to the shore here but I haven't found much. SWF is on the case. Coach Mike suggested checking the waters out the day of the race to see how things are or just skipping the race and concentrating on the NYC Tri. I thought about maybe switching to the Duathlon instead of the Tri. All of this and I don't even know if I'm allergic to a jellyfish sting- but the fear of dying from my allergies is too real to ignore. Anyone know anything about jellyfish? Advice wanted, please!
