Audio story ideas

For my audio story, I'd like to do a bit more preparation in order to secure the story and the interviews in advance. I really, really want to interview the hot dog guy for this story. I think the audio aspect would work perfectly. I would interview the vendor about the who/where/when/why/etc. aspect of his business while also interviewing customers as to why they are here.

For natural sound I could record people ordering their food and also pick up the noise of cars passing on York road. Perhaps even pick up the drunken banter that is so common on that intersection. I feel this story has a lot of potential. It's just up to me to make it to the corner on an upcoming weekend night and talk to him about it. Right now, this is my first and only idea for this piece. His answer will dictate where I go from there.
