This is up in the NC mountains near Tennessee. Last week brother was weedeating. He got a tick bite on his belly. A few days later, he showed it to me. There was no "bullseye." There was a round disc. It was about 2 inch diameter, and a bright rosy red color, no kind of rings the entire disc was red. I told him to get his ass to the doc.

Four days after he got bitten, brother went to the doc. Doc said it was Lyme disease and gave brother a 14 day scrip for antibiotics.
Lyme is no problem if you get on it early.
