I park at the rec center lot and walk down the wash usually because they close the park gate at sunset I believe. I have never float tubed there but I do have one. I don't know if I would want to be seen float tubing down there, some people have told me that the parks department people will take your gear if they catch you fishing. Others have told me that they don't ever bother them at all. If I see them comming they won't see me thats for sure. Its not worth the risk, I usually don't fish where they can see me anyway. If I had to say I don't think they care too much because there are people swimming down there and the signs say no swimming and they don't seem to get harassed. Good luck down there!
