Last year's Kids Day video - yours truly shows up somewhere around the four-minute mark.
The lady and I stumbled upon a huge kid-friendly family festival/parade in Mexico City (two photos above) last weekend, and it made us positively homesick for Franklin Avenue and the Kids Day, which was some of the most fun either of us had last summer. If you're in the neighborhood, don't miss it, and if you've got even a few hours, consider volunteering. People will be setting up from 8am, and the event runs 10am - 5pm, with clean-up afterward, and I guarantee that if you go intending to just help out for a little bit, you'll end up having a blast and hanging out until the last child has wandered happily home. If you want more info, contact the CHCA, or wander into About Time or The Candy Rush, where they'll tell you all about it.
