I actually live in Lewisville. There are some decent areas and some ares you dont want to live in. Two neighboring cities ar Flower Mound And Highland Village. The housing is a bit more expensive than most of Lewisville, but not outragously over priced. The whole area is a typical suburb.
As far as concert venues, for any big name artists, you'll most likely be heading to Dallas or toward Fort Worth.
I actually work in down town Fort Worth. It's about a 45 - 55 minute drive with no traffic. Dallas is about 30 - 40 minutes with no traffic. I cant really say about getting to down town Dallas during rush hour. No accidents on the freeway, I'd say an hour. If there's an accident....... no idea.
If you're looking for acreage, depends on which direction you want to go. How much the land is depends how far out you want to drive. My parents bought some land about 8 years ago for 10,000 an acre about 35 miles north (40 minutes) of my house. Again, I'm about 30 minutes north of down town Dallas.
