As mentioned, Walmart is everywhere except along the highway. I would suggest getting Good Sam roadside insurance as changing a tire along an Interstate is not fun. Check out flares and road emergency warning signs. Also, I was advised by a Mississippi Highway patrol officer that they suggest call 911 or 411 ( what ever the emergency number is in the state your in) and ask that a patrolman come to your assistance if you are topped along the Interstate. H said they would rather park behind you with the lights flashing and do routine paper work, than cleaning up an accident report. In most states it is the law that you must move over a lane if there are flashing lights. I would suggest that you try placing a small piece of masking tape on the items that you take. As you use the item, remove the tape. At the end of the trip, remove the items that still have tape. Now you know what not to take on your next trip.
