Absolutely wonderful! If you like the wilderness and a slower pace of life, then visit Wagonhammer, a nicely laid out park on the banks of the Salmon River with 50 Amps throughout, full hookups in the middle and water/power on the river edge. WiFi is good with several towers, and there is tent camping available, too. The owners have set up bug attractors everywhere so there were very few bugs around. Be aware that there is no cell signal in North Fork. Salmon has great cell service and LTE when you go down shopping. Limited foodstuffs in North Fork, but they do have a gas station.
It's a nice, clean, and well laid out park that is typical for this part of Idaho. Around the outside are backins with 50A and full hookups, and in the middle are 30A sites that look like pull throughs but are not as the utilities are right at the back - so unless you are doing water/power only, you will need to unhitch - no biggie. There is plenty of room between the spaces, with small trees - enough room for quad slides (just). WiFi is OK but there is only 1 tower, and so if you don't have a good antenna on your laptop you may find the signal to be weak. I always carry an 1W external USB adaptor with an antenna and it's fine for me. We paid $25 for a full hookup, 50A site with Good Sam - I'm very happy with that.
