it took us like 3 weeks to rid ourself of them.
Duhhhhhh... how's that. You find one you should shed and inspect and all that. If you're in known tick country you should do it even if you don't find any. I can see it maybe taking a few hours from park to find you have them, but certainly before I went to bed that night. WEEKS???? You can catch about the worst thing in the world from a hooker in Mexico and not take 3 weeks to get rid of it. At least that's what my buddy told me. I wouldn't know.
