My entire family is from Texas. Specifically DFW (Dallas/Fort Worth Metroplex). Plano is part of DFW. I lived in Mesquite (East DFW) when I was a kid and have visited Texas almost every year of my life since.

DFW is huge land-wise. It is bigger than some states. Lots of money there. The area is pretty clean from my perspective, but I never spent much time in Plano.

Texans are proud people, which you have probably already heard about or experienced for yourself. There is plenty to do in regards to nightlife, entertainment and outdoor activities. You name it, they got it. They are even building a mountain for snow skiing.

It is hot and humid there, so, like Skunk said, "water!"

As for Texas in general, there is just about any climate or land type there. Swamps in the south, mountains in the north, plains in the west, deserts etc etc

If you like beef, you'll love that place. There are a BBQ joints on every street claiming to have the best steaks on Earth.

Hope that helps.
