I was really hoping to find a super cool hinge to work with today. The kids were give free passes to Silverwood for reading 600 minutes above and beyond the required reading for school and I promised them that the best time to take them was during my vacation this week. We had a wonderful day at Silverwood and I lucked out in finding great hinges today. Here's a close up of the hinge I took at the "train station" at Silverwood on some trunks.
