Looks interesting. I gave it my zip code (95051) and it returned two conventions: one in Burlingame, which is ~25 miles away. That's reasonable. The other is in "Columbus"; all I know is that it's ~2000 miles away. I'm assuming that's Columbus, Ohio, although I haven't checked. Regardless, I'd rather see one result that I might possible go to than two results where one of them is literally thousands of miles away; you might consider tweaking how you determine events to be relevant to users.
