I pulled 4 of these bastards off of myself and a kid in the last 2 weeks. That's more than I've had to remove over entire summers in the past (both as a kid myself, and when my own kids were smaller and more prone to roll in the dirt). They are definitely everywhere now.
Also learn to identify the symptoms of Rocky Mountain Spotted Fever , the other nasty thing these ticks can carry. It's easily treatable if you catch it early, but can seriously fuck you up or kill you if not.
