You'll get a tip every Sunday...take it or leave it!
More specifically...find a farmer's market in your vacationing town or city. All the knowledge is there. Why? Because all those people are local and locals know where it's at. Here's an ideal concept...you don't know everything...so ask and listen to the people who do. I chatted it up last week at Sedona's Farmer's Market with a dude who makes flax seed. I can't stand that crap, but the guy was nice and gave me some wonderful things to do on vacation. He recommended that we take a afternoon trip to a small town called Jerome. I listened, we did, and it was the most fun I had on the trip. And I bought a package of his flax seed. Gotta support the little guy!
