I live in Pasadena on the beltway near 225 so not far from LaPorte. Pings out here are few and far between but you can get them. There are no surge zones out here and the guarantees will never apply here...unless it's by some miracle.
Most rides will take you from here down to the Clear Lake area or back into Houston (at least in my experience). I once got a ride from Channel View all the way to Pappasitos off Richmond. The only bad thing is you have to come back here each time to pick up if you have no permit for Houston.
