Just 15 minutes N of Lubbock city, still in Lubbock county, this is a major speedtrap. No I don't mean that if you go 6 or 7 miles over the speed limit they ticket you. I mean that if you go 4 or 3 or even 2 miles over the speed limit on I-27 they will ticket you. My suggestion? Drive BELOW the speed limit until you get out of Lubbock county going north, and DO NOT, EVER, stop in Abernathy for anything - not for petrol, not for food, not to look at the sights. Drive through and forever forget about the place; spend your money elsewhere. Fair warning.
This little warning isn't anything bad. Just so you know, if you like to have an occasional drink, the only place you can get it is in a bar/club or a restaurant. Lubbock is in a dry county. No alcohol is sold in the grocery stores and there isn't any liquer stores.
