Free water, clean area, picnic tables and bathrooms.

Wyoming welcome center. I stayed two nights. It has restrooms, dog park, free water, Sewer, & garbage. Really nice to walk around. Free WiFi in building only.

The welcome center (bathrooms inside) hours vary so you'll have to check ahead. Commercial truck parking is separate which makes for a quiet rest. I've read that technically there is a 4hr max visit but I have stayed overnight more than once without ever being hassled. The 3 star rating is only because the building is closed more hours than open.
