There are very few things in life that I consider worth getting out of bed before 8:00 on a Saturday morning. Market at the Square is probably at the top of that list.
The market is an abundance of local and organic produce, meats, and baked goods. There are artisan goat cheeses from a local farm, lots of grass feed meat and poultry, and all sorts of goodies baked by small home bakers and Amish families from the communities south of here. There are all sorts of unique arts and crafts that make the Market a great place to go if you need to get a special gift for someone difficult to buy for. There's a wonderful upbeat vibe that is largely due to a delightful one man band who has turned singing the alphabet into an art form. And let's not forget the kettle corn!
I would recommend getting to the Market as early as possible so as not to miss out on anything. I've had some very sad mornings where I've succumbed to the snooze alarm and just missed getting the last quart of plump, sweet-smelling berries. Don't let this happen to you! Get to the market by 8:30 or 9:00 and you'll be treated to a wide selection of whatever local produce happens to be ripe and a variety of other wonderful items. Be sure to bring cash, as some vendors don't accept checks or credit cards.
One word of warning: There are a lot of political and religious organizations with booths along the north edge of the Market, where you will likely be approached to sign a petition, offered flyers, and the like. Generally, no one is too pushy and a polite "no thank you" is all it will take if you don't wish to partake. Be particularly wary of the guy offering free stress tests; He's a scientology recruiter.
