No kidding. Where does the exhaust from every boat go!
Aw, c'mon Mike - boats don't have exhaust! They'd need mufflers if they had exhaust! I bet you can't run a snorkel on a BOAT, either - you just KNOW it would lead to some kind of hooliganism! So...
I should be able to wheel my vehicle with Colorado tags (and a snorkel) there, because it's legal in Colorado, right?
