Nothin that I know of
Get stuffed up and itchy eyes around pollin from those damned trees that are everywhere back at home, but nothin dangerous
....I got stung about a dozen tims in my scalp last summer and a couple more on my hand when I was playing paintball in Whistler and hit a wasp's nest, and didnt have a problem (other than the excrusiating pain
), so I think I'm good
