It's not only what the OP does or doesn't do, but the previous campers. Anything from mice to a bears become conditioned to free handouts or careless campers. While I agree Wausau is a tad south for bigger bears, the be prepared motto always applies. Not only for yourself, but because of those that came before you.
Are you speaking of the Mountain Bay State Trail by any chance ?? If so, I didn't know camping was allowed. It's gonna be a scorcher weekend by the way. And that means muggy as you know what.
