I didn't know that people moved to Friona anymore?!!? I grew up in Friona and my parents still live there. CanyonAg was pretty spot on.
Nightlife: There is none.
Demographic: It does have a high volume of Mexicans...illegals if you will.

Everyone is pretty nice.
Food: Tasty Cream is your best option. They make a pretty good burger and chili-cheese fries.
Smell: Canyon is kind of right. It smells like cow manure most of the time. It is really hard to get away from that smell.
Schools: They aren't too bad. I felt like I had a quality education, but I took all AP & Honors classes. I know some of the teachers and administration and they are all good folk.
Other things, it is mainly a farming community, but the big employer in town is Excel which is a beef processing plant right outside of town. If the wind is right, then you can smell the plant in town.
Overall, it is a quiet town. There really isn't much that goes on there. It isn't a bad place to live....if you can get used to the smell.
If you have any specific questions, then don't hesitate to ask.
