Thanks everyone. After talking with the boy, we decided to not go the rustic route and do any fly-ins (someday I hope too....). We were able to get the trip moved to the first week in September, and will keep an eye out for road closures/issues with the park.
Since the plan is to still rent a vehicle, but not go to Denali, do you recommend a different location to check out? Maybe fly into Anchorage?
I appreciate your help.
