ERA Aviation in Anchorage offers flightseeing trips in 2 rather beautiful DC-3's.
Check them out
here.
I was involved in operating one some years ago. It was a beautiful machine (had a fortune invested in it) but was very unreliable, principally because it was seldom used and got upset after being cranked up every few months after all that idle time. Like so many good aircraft they thrive on being used all the time, and definately enjoy a good reputation for reliability.
Until a couple of years ago, Air North was regularly operating passenger service with them, until they replaced them with the traditional DC-3 replacement, HS 748's!
The march of time and progress may be a little slower outside the centre's of civilisation!
If you ever get a chance to check out a DC-3 on ski's, don't miss that opportunity.
Still have to go and check them out every time I see one though. Great aircraft.
