Talara has water shortages all the time, so I'd suggest you bring lots of water (joking about bringing it but they don't have a lot of potable water). Also, they don't have movie theaters, mall (I don't recall one there), and stuff that isn't made in Talara is pretty expensive: ie, razors, vitamins, medicines(ibuprofen), etc. My girlfriend's family is from Talara. Really my biggest complaint in the short amount of time I spent there was the amount of dust that is everywhere.
On the upside, you are close to the beach, life is relaxed, the cebiche is to die for, and the girls are cute (if you like girls that is). Enjoy your time there!
