Seems this thread has morphed away from the levees, but I just saw it and have a suggestion for the Dallas City Council, the Corp. of Engineers, etc:
Instead of building an artificial whitewater park (on the Trinity? C'mon! Sounds like a Farrelly brothers movie) how about a moto-park for ORVs? I mean, it exists naturally, just some grading, signs, pic-a-nic tables.
Oh yeah, I forgot - ORVs are not environmentally friendly. Not like an artificial whitewater run with attendant pumps, etc.
I live in east FW off 30 and Oakland. The woods around there are off limits BUT very rugged and untamed. The city owns it all and it would be the perfect spot for an off road park. Theres even a parking area over by channel 5.
I look out my back door at it all and just wish n dream.
