"Waif" ~ Fausse State Park, LA (c) 2011 Skip Hunt
I have never encountered quite the level of aggressiveness that pervades pretty much everywhere I went in Southern Louisiana. Well, Belize was a little worse but still.
I usually fend them off by eating raw garlic. You sweat it out your pores and they avoid you like the plague.
I'd allowed someone to convince me it didn't really work, but now I think next time I'm in the bayou I'll definitely be armed with a cache of strong cloves. ;-)
