GLWS It is free, and you are taking a loss for giving it away for free, I'm sure!!!
But in reality, it is hard to find someone to take such a tank. Everybody want's it, lol. But to get a crew together and pick-it up is another story. Just keep putting it up and somebody will eventually get it. It just takes the right person to see it. I just seen this thread today for the first time.
I saw the other video and WOW, that was a sweet ray tank...
Like I said good luck. Hopefully somebody picks it up for you. sorry you have to part with it for whatever reason...
