Cell Phone Coverage is gotten either by going out to Big Piney, La Barge, or Smoot. It is 6's in most places to which route you go.
The better grocery store is going to be in star valley and the better road is probably going to be big piney. La Barge road is nice other than one section that completely makes it not worth going down.
If there is a trail, it will probably have a side by side. That side by side will probably have county 4 plates.
There is no shortage of camping areas, but I would recommend picking an area that isn't close to a main road. Unless you like Side by Side noise.
Side by Sides are a great tool, but a lot of people probably need to get off of them once in a while. Then again people kill elk every year just by covering ground.
The weather can be sunny and 75 or cold and -20. It could snow or rain as well. Most often snow.
There are always elk you can glass on Wyoming peak. Only a crazy person would ever attempt to kill those elk.
There are elk to be had on that peaks side in and out of the pockets of timber, but it is rather steep in a lot of areas.
Sometimes, it can get so steep that you struggle to even set up and shoot an animal without the fear of sliding down the mountain to your doom.
As for other areas. Pretty much any creek coming off of the sheep pass side all the way to the end of the unit will hold elk. Park at the bottom on the Grays river road and hike up the creek. As long as someone that day does not have the same idea, there is a good chance glassing as you go you will see elk.
Whether you can get to them and kill them, is the challenge of the area.
Elk in October generally do not hang out in nice places where they are easy to get too and kill, though some like to run by side by sides I don't think that is an effective strategy in the area.
