Greetings all... I'm getting ready for a trip to Niagara Falls (along with Toronto, Corning & Rhinebeck), and I'm concerned about water and my Canon 40D. Naturally, most of our activities will be geared around the falls for 2 days, however I hesitate to be without my camera for any length of time. Are there any locations or sightseeing expeditions where I should definitely leave my camera behind? Thanks!
