Buses in Alaska

Just a few pictures of local tour buses in Ketchikan and Skagway, Alaska.  Enjoy.

Are there arctic design like bodies and windows for these buses?

The ones in the photographs do not appear to have any specially designed windows or bodies, and I didn't encounter any.  It seems tourism really dies down after the Alaska cruise season which runs from May through late September, so I surmise there are no needs to install winter equipment on these tourist buses.
