We stayed in a lovely dispersed camping site on Mosquito Creek road in Wilson, Wyoming.  Some of the campsites have views of the creek and are very private.  All sites are very private.  

The road to get there, as is usual with dispersed camping, is very bumpy and 4WD is recommended.  

Our friend saw a large black bear after leaving our site.  It is also moose territory.

Gorgeous, private, but with no bathrooms or amenities at all.

Even though there is no water, bathrooms, or other amenities, it is free.  And it is a few short minutes to the town of Jackson Hole.

Bonus:  we have cellular reception enough that I could make calls and send emails (Not strong enough to send pics and stream though).
