Likely you won’t find parking at the flying J because it is sooo packed with trucks from the distributor centers in the neighborhood, BUT there’s plenty of street parking along the road that runs next to/under the highway. Lots of trucks, they will purr you to sleep and turn on to wake you up in the morning 🤣

Has signs that states 2 hr max parking. Got there late at night and there were a lot of other vans and car sleepers so I risked it. At 5:30 the security guard came around knocking on everyone’s window. Moved over to the 7/11 across the street for a few more hrs.
