Largo Central Park has a "miniature train" that runs the first weekend of each month. We went over to check it out this morning and it was pretty great. The line wasn't too long, Emerson and I got to sit up front, the ride was a good, generous length and included going through a very dark tunnel and over a bridge above water, and it was really fun (and free!). There was also a great playground nearby where we played for a while afterwards. We will definitely be adding this to our list of fun things to do with the kiddos on the weekends.
