I must have collected a bushel off my camo so far this season!!

I've only been bitten once, yesterday, in a spot you'd rather not be bitten at all...I am allergic to their bite w/ localized itching & swelling; consequently, I know if there is one drilling in so generally they are removed pretty quickly.
I've gone through the treatment for Lyme disease a few years ago, the antibiotics took a toll on me themselves.
I recall a time when there were no ticks here at all; what happened?
It's one reason I'm looking forward to colder weather.
