A couple questions, Anyone go to Alaska to specifically bird (upland or waterfowl) hunt?

Is it too expensive to just go bird hunting there? And if you do, what do you normally do about the bears? Do you keep a couple of slugs or buckshot in your pocket just in case. Or is the noise, movement and shooting enough to move them out of the way? Or listen to the 'Bear activity report' on the radio and stay out of that area altogether?

If you drive from the lower 48 how do you get through Canada with a shotgun and ammo? No problem at all? Too much of a hassle just borrow a gun?
