Is there any other (legal) way of putting bears off ? ( i.e.Gas or flask bangs ) I am aware of the food problem and intend to use the rope/tree thing when wild camping.
I know it sounds like a daft question but being a Brit it is not easy to get hold of a gun/rifle in the US/Canada (AFAIK).
Its not that that I have a problem with them, I used to be a soldier, its just that the last time I had one illicitly in a foreign country (Brazil) I came close to spending a long stretch in jail.

For a while, life was not very funny.
