I grew up in TN, UT alum...GO Vols!
Haven't seen the fire ant thing here yet, nor experienced them growing up. Our yard in TX was just FULL of the damn things, though. And sure enough, EVERY time I bought a new pair of cute summer sandals, WHAM! I'd get bit a couple dozen times. Then, as some of you know, you have these really attractive pustules with red borders erupt from each bite, which yield to open sores and finally slowly heal to purple-y scars that don't go away for a couple of years. I f'ing HATE fire ants.
AND in Texas, I once picked up a piece of firewood that had four (4!) black widows on it. You bet I did the "creepy bug" dance!
Yup, I'll trade the bug population in TX for that of Tennessee any day...
