The next festival in my local area is Westfest, a Czech heritage festival, on Labor Day weekend. My boss has been involved with it ever since it started. It's a pretty big deal...polka music, beer, sausages, kolaches, arts & crafts.
Then a couple weeks later is Middlefaire, a small fairly new Renaissance festival. We will have a booth with the candles my daughter makes and my husband will have his leatherwork.
Not really crazy festivals however!
