Do you ever go where local tourists stop? The veranda of a hotel, an outside dining/drinking/ice cream spot? Do your ears perk up and tune in whenever anyone's talking about real estate? Tune in to comments about your locale, as well, whether they be tourists or locals out and about.
What frustrations do they have? What excites them? What do they enjoy? What's been recommended to them and how do they feel about it? Their remarks are more apt to be honest when they aren't responding to questions or surveys.
The information you gather will not only be useful knowledge about your area, but many of the topic could also be Blog Fodder.

sHARON: Along these lines, last spring was at a education day at our board and went next door with other agents for some good bbq, we of course were talking real estate. Had a couple come by the table and said they were evesdropping and could we help THEM with a possible purchase. Could they have our cards? I was the only one with cards on me!
They did actually call me a week later.
Chris - I love it - Musical Pies!
Barbara Jo - I also leave cards in the airline magazines and in the chair backs.
