Took tenative itinerary to boys. Also gave them these suggestions. They love everything. Per parents, they are busy googling and planning. Thanks!
Oh, these very civilized boys almost went into shock when they found we would have long periods with no wifi. Hate to sdmit it, but I had way more woodcraft and outdoor experience at their age then they do. A LOT! They think "roughing it" means no wifi for a day. Camping means spending the weekend up at the inlaws trailer in a snazzy resort. Wildlife are all tame and cute and benevolent. They thought they might approach and hand feed bison like they do their other grandpsrents' horse and dairy cow, and that they could scare grizzly bears away by shouting and waving their arms. I am going to enjoy watching their minds expand.
