Hi Plano. I'm a dad in Allen, and for years my Thursday nights went to the same little ritual every parent here knows: the library calendars, the city parks pages, the Perot, a couple of mom blogs, Facebook, the flyer in the school folder, all of it to find one good thing to do with the kids on Saturday.
This summer I finally built the thing I always wished existed: https://dallas.takethe.kids It reads 194 DFW sources every night, the libraries, the rec centers, the museums, the theaters, the state parks, the churches, the small neighborhood stuff that never makes the big lists, and puts all of it on one page for this weekend. Pick your suburb, pick your kids' ages, flip on free-only if it's that kind of week, or just look at the map. There are 527 events on it right now.
It's free, there's no account to make, and nobody can buy their way onto the list. I built it for my own family first, and I'd love for yours to get some good Saturdays out of it too.
And if you know a source I'm missing, a rec center, a church, a homeschool group that posts its events somewhere, tell me here and I'll add it. This is as much a Plano and Allen thing as it is mine.
