OK, now that it seems this is a working hiatus from the website only for Peter, perhaps we really should suggest places for him to go and see new interesting things, aside from the places he always goes, like skiing in the same old places. Perhaps next summer he should try skiing in South America somewhere?
As for places that I can suggest that I've been to, and one that I'm planning to revisit, Yellowstone is it this year, taking a hiatus from the Everglades I think, since the truck had issues last year and may still not be quite right.
As for me, I'll be there at the end of August. Though the rapids for the rafting trips in Jackson Hole are their best in mid or the end of June. Waters cold, but the waves are awesome, the kids would love that. However I have to pick from the weeks offered, so I'll have milder waves, but warmer water.

The first two weeks of September I hear are not bad times to go, less people, but the chances of snow at night increases and a lot of facilities start to close. OK, if I could of had them, that's when I would have gone.

The whole area is full of wonderful things to see in the mountains and the animals. Just keep a distance as the animals are wild and not friendly cartoon animals. The Grand Tetons are just south, the moon like, though starting to bloom landscapes of Craters of the Moon in Idaho. (probably won't make it that far this trip as I want to concentrate on Yellowstone, but a neat place) Devil's tower isn't far either for the Close Encounters of the Third kind fans. Stayed at the KOA there years ago.
Yellowstone in many ways is an over touristed area, but for good reason. We can thank Theodore Roosevelt for believing it should belong to everyone and was in need of conservation.
Going to visit an old friend in the Riverton, WY area while I'm out that way as well as stop and visit a cousin in Minnesota on the way backish. If there's time we may run up to the Thunder Bay area of Canada. Am sure to meet some interesting people on the way. I'm camping, but there are a lot of hotels, lodges and stuff in the area as well.
Worth the trip.
