This was the 50th year for this event held in Westminster, Maryland. Hundreds of antique tractors and farm machinery, antique cars and steam powered equipment, some of which is used to give working demonstrations during the day. Some of these things are very ornately decorated, making them as much works of art as valuable, purpose built tools.
There are also a lot of flea market type vendors selling anything and everything including things which you'll look at, scratch your head and ask yourself, "What the heck is that?". A fun way to spend a day, this year they even had tractor pulls with some of the antique tractors.
