A while back I had found a 10 gallon fish tank for free. I thought it would make a great terrarium. I've had enough fish tanks and their care, thank you very much. With it being that big I even thought it would be fun to do it as a diorama. My wife asked what I'd do with it. I told her if we decided we don't want it that we could sell it. She said most people that would buy one would be women so she is the main designer. It's going to have an N scale train, fairies, and unicorns. I picked up these 4 cars off Ebay for $18. I was really surprised with their quality considering they older Model Power. I was also able to pick up 6 pieces of track for extremely little at a garage sale.
