For the Texicans on here, is McAllen considered E Texas?
No, it's part of Northern Mexico. It used to be in deep South Texas.
Just curious, as I haven't spent much time in your state. But recently was a guest of that fine city for a good while. Wasn't sure where the dividing lines are.
If you look at a map it will be quite obvious that's as far South as you can go in TX without being in MX. Might as well be MX though, as I hate the place. Toledo Bend Reservoir is as far East as you can go in TX, and I love that place.
