I've been going to the market since it started, almost 2 years ago. I love the way the market has grown. There is something for most everyone, it seems. During the summer it is hot (duh) but everyone from the vendors, to the customers to those running the show (you know who you are) are so friendly and there is water and shade everywhere you don't seem to mind (too much).
With the market being right downtown, it's nice to take my wheelie cooler, get my veggies for the week and walk on over to either Postino's or Liberty Market and grab breakfast. I haven't tried the food trucks yet but I think that once the cooler weather hits I'll grab breakfast there and sit a while and enjoy the music while I watch the rest of the shoppers.
Remember to bring cash ~ some vendors do have credit machines but it doesn't hurt to have it anyway and bring your own reusable bags.
