Heck, just go to the corner of Business 121 and 35 in Lewisville. You will swear and be darned that you are in Mexico.

Me and a couple of buddy's go to Port Mansfield every year to fish. While we're down there, we always jump over to Matamoros. I'm no expert on Mexico, as this is the only place I've been, but we always have a good time while we're there. Lots of shops and restaurants. Don't know if they have any donkey shows there though.
