I enjoyed the hessler street fair... Perhaps mostly because its close enough to home that I was able to ride my bike there. I did not stick around for any of the entertainment. There were a few interesting vendors selling some products that I had not seen before. However, they seem to be fad type items you can find the instructions to make on your favorite fancy/fab type website.
One quick stroll through was enough for me... All said and done i was there for at most 40 minutes. Would visit again just for something to do but would not miss out on other adventures just to go to this fair.
