I'm collecting TP scripts for obscure/interesting locations in Ur. A good example is the hidden underground chamber in Maale Bads. I don't know all (or even many) of these locations so I'm looking for your suggestions, as well.
If you know of any hidden/hard-to-reach/just plain interesting spots, please reply here. If you happen to go to one, please make a TP script and mail it to me.
