Yes, many people cannot understand how big Texas is.... you can drive for a couple of hours and still be in the same county..
Here in the metroplex, when people ask how far something is, the reply is in time, not miles, though. It might be 10miles away, but a 40 minute drive.
Now, when you get out in west Texas, the roads go on forever.... the temptation to, um, bend the speed limit is overwhelming. I'll be cruising along at 75-82 mph (limit is 75) and people FLY past me, looking at me like I'm having car trouble..
