Has anyone considered doing this or talking to the city about doing this? If they would just bulldoze the wall on the far side it would be pretty easy. It fills fast with rain so just rebuild the wall and let it fill back up.
Found a couple of dics at WW last weekend and the phone numbers now belong to a couple-a-jackassez. So if you lost a disc on 5, 6, 7 or 8 let me know what you lost and I'll stop throwing your discs and get them back to you.
I've found some classics in the pond at PC. The phones have all been disconnected. If you have lost some old stuff out there let me know. My guess is people will want this stuff back and I have no interest in throwing it. I think it's been in there for awhile too.
Here are a couple of good sites that people have shared with me which come in handy when figuring out what a disc will likely do and others similar to what you are looking for. You may have seen these before, but for those who have not, they are really helpful.
