We live near rail road tracks.
For the first time in the year that we have been here I took Chris over to the tracks to lay pennies down. He was really excited because he thinks that pressed penny machines are the coolest thing ever, and whenever we go somewhere that is his go to for souvenirs.
We are planning a trip out West this summer. One of the really neat resources that I found was this site. You can locate pressed penny machines anywhere (how cool is that?!).
We laid the pennies on the tracks on Saturday (there were 10 of them) and on Sunday when we went back to the tracks to retrieve them we could only locate two. They were prefect and Chris was excited. The missing eight made no difference to him. Next, we are planning on putting down different coins to see how they press on the tracks.
