Thanks for the links. I had found the NPS site and learned a lot about Denali. We are planning to take the long tour bus ride to Kantishna. My preference was the 'shuttle bus' to the Eielson Visitor's Center but my wife and the AK travel agent preferred the 'butt buster' 13 hour trip! We have pretty much finalized the itinery but don't have tickets or reservations yet. Got to get that done real soon before everything gets booked up.
