Great question you pose. I sell things on craigslist from time to time and I always wondered what type of nutjob I was giving directions to my house to. I've started meeting people around the corner at the local shopping center since.

My wife met a girl at a industry type social event and the girl expressed interest in meeting with her to discuss how she got started in her own business and some of her design tactics, etc. They met at a public park in the middle of the day and we even went so far as to record the clothes she was wearing (she can be a little paranoid), 6 months later, the new girl and her husband are great friends of ours.

You're probably going to be fine, but I believe you made the right choice in waiting until someone else can accompany you.
