We were out for a ride the other day (love to get lost on a ride) and came upon this action. Fantastic! I had never seen the pumpkin throwing Trebuchet / Catapults before and these were the real serious guys we came upon.

I put on my brakes when I saw the location and this Crane with a huge ball and chain that definitely squashes things. Had to take a look!

The whole layout of the grounds was just breath taking if you like stone, land and big heavy machinery. (I love all of it!) I love that. lol

So we stopped got out as curious as the next person who drove buy the place. It really is exciting to watch believe it or not. You got the sense these guys really got into it and had a ball doing it.

You knew right off they had to be people in the crane industry you know the ball and wrecking kind of thing. I had fun and so did my husband and daughter watching them have fun that's all that counts.
