How does having a warranty make me not worry? I am not interested in a warranty. I want wheels that won't be affected, not wheels that will fail but can be replaced.

If the wheels get gummed up during the first snowfall in December, what good does a warranty do me? Ship the bag to B&R and wait several weeks. What bag am I supposed to use during those weeks - is B&R going to give me a loaner? And then when the fixed bag is returned, what happens during the next snowfall?

This is indeed a possible solution, as is taking a taxi from the hotel to the job site. If no one can point me to a bag with "winter wheels" these may be my only options. Surprising that other consultants in cold-weather cities haven't had issues with the snow. Perhaps all bags are snow-proof these days?
