Okay, I get the idea of making noises to scare them off.
And, I thought of you, Disneyphile, when there was a big giant mosquito right outside my front door last night {I also do not like bugs and will see/feel them everywhere once I've seen one....summertime, fleas, freckles, PITA}.
True, I shouldn't be too afraid of bears. My s-i-l chased off a bear that was getting into their food supply during the night. Scared the kids she had with her senseless. {have they gone back? no.}
BUT my idea of the tent is that the bears are not stupid. Sure, they can get into anything, tents, cars, etc. But, they know better. I think they feel what ever is out there in the open is for them.
Something that always stuck with us was seeing a motorcycle with a big bite taken out of its' seat.
Why? Did they person have food under the seat {a secret compartment?} are a very bad case of gas? Hmm...{it was so like 'Where's the cream filling??}
OH and, anyone see the film about the guy who was mauled up in Alaska with his girlfriend by the bears? It was a very interesting movie and the talk here about no sex made me wonder if that could be what did them in? {no conversation value here unless anyone also saw the movie.....
