Do you really want suggestions on killing time in Rock Springs or around Rock Springs? I worked there in 1979 .....
Lol, key word is worked there

) The "Rock" is not a vaction stop but they do have a world class recreation center and very friendly people . Flaming gore just to south is pretty though,and the green river has some good fishing. I would agree with Phil on not needing chains that time of year. If you run into a spring storm you would probably wait it out pulling a camper. Just remember never to drive around the gate if they close'em on the interstate

) Loved Wyoming,a place where calling a woman" darlin "is still a compliment, everyone still has a sense of humor and the term "you bet" covers it all.
My Thule's are are diamond style,they fit in a compact case that stays in the truck. If you are looking for a new set to have for the ramps then I wouls probably go heavy and get the peerless or equal. I don't think you would ever wish you had less chain when the times to use them.
