Radio stations are rather reluctant about giving publicity about the opposition!
Even the BBC local radio stations try very hard not to mention other BBC local stations!
I do a local radio show in Texas every weekday. It's called Geek Free Radio, and can be found on the net at ksetlive.com I'd be happy to help your group in any way. I've been trying to get some members of the local caching group to come on the air with me, but nobody in that group seems to want to respond to any emails. If you can somehow get in touch with them, and pass it to them over the pond, then they could place it here in Texas, would that help? I'd be glad to have some of you live on the air via phone, as well as someone from the local group. I just can't get in touch with them. I thought it would be a nice technology related show to gain some interest. I personally don't do geocaching. If anybody wants to pursue this, you can email me at geek@ksetlive.com
