Bring lots and lots and lots of reading material or some type of project. SMB has a waiting room with comfy couches and free coffee
. They have wifi BUT, the do not know the password
Its an industrial area so nothing fun is near. The last time my wife and I went, we got a room at the Picadilly Inn and stayed there until our Rig was ready. Wifi was free, air conditioned room, TV, ordered Pizza, etc. SMB dropped us off and picked us up when our Rig was done.
Don't know too much about campgrounds. SMB staff can probably recommend something.
Are you coming form Alaska?
