Do we know what the swap meet was about? Was it for cars, a hobby, electronics, what were they swapping? My husband used to go to remote airplane swaps. You could get parts that you needed for your hobby. So if you knew what she was into, that would be a lead for FBI. I also think that the braces may not be something she would have to do right now, but at some point if this case drags on, that is a place to get information out too. It is also not cheap to keep up with the cost, so if she ran away, she may decide to have them removed. At any rate, that is 2 places to look at. I think TX is also a place to check out old friends and to see if anyone kept in contact with her. Her phone is gone, but you can always get another phone without leaving a footprint. You can use prepaid visa cards, and load them up to pay for stuff, again, no footprint. If you live with someone and they have everything in their name, again, you are off the grid. Some jobs will let you work under the table, like home cleaning, or some bars or restaurants. But cleaning, or doing landscaping are a good way to get paid cash.
