Just voted on campus at UT-Austin! My anecdote is particularly useless since I can't compare it to a previous prez election here, but I think it looked decently, if not overwhelmingly, busy. For 8:30 am on day one, I would guess 25 other people were voting there at the same time as me, and the stream was staying steady.

addt'l TX anecdote: voted this morning in NW San Antonio. Suburban polling site in whiter-than-average Dem-leaning neighborhood. 40 people in line. 30~ of them broke out into a "Trump" chant -- delusional. SAD!
