It depends on what area of Dallas you are looking. I am in the PlanoAllen area, my house backs up to an 85 acre park. I have wildlife (bobcats, armadillos, coyotes, raccoons, etc) on a daily basis.
You CAN live in the concrete jungle if you choose but there are some VERY nice options. You'd never believe our neighborhood was in the DFW area.
We don't do the water park thing so I am not much help with that. I've probably been to the Arlington area 3 times in 20 yrs.
We love the DFW area and would not choose to move.
