Ummm yall have bigfoot down in Texas...
Depending on where in Texas you might even have to worry about the "Skunk Ape" which has been known to be more aggressive than the creatures sighted in the Pacific NW and Canada.
Besides time constraints, depending where in Canada we are talking about you might have to worry about what would happen if your plane is forced to land in NYC or NJ due to Weather.
Like others have said, borrow a gun from family while up in that there Canada. Easier and much less risk involved.
