yea, I get your point Gary, I my somewhat humorous point was that I saltwater species would have a hard time making it from San Antonio to the gulf and not be a tad bit crispy by the time it arrived.

but it is a valid concern, as blueboy said, I used to work in san marcos, and am well aware of the damage being done there, I mean heck, if you want to see what an invasive species can do, just look at all the elephant ears growing on the river bank, some idiot at aquarena springs thought they looked nice, and they move further down stream every year.
