I spent an enjoyable day with the family. We took my nephew to ride the mini train with the Orange County Model Engineers, Inc. According the their brochure, there are 20,000 feet of track located over 40 acres of property. The property that the small trains run over is simple green grass dotted with trees. It's a no-frills operation.
The train ride was quite and peaceful. I was a wonderful experience and I wished that I lived closer so that I could visit more often.
If you live in Orange County I highly recommend visiting them. Please take a look at their website for more info.
