This is one of the more unique parks in the area and it's close to highway 40, so it should be easy for most dads to get to.
The start time says 1:00, but most dads float in as preschools let out, lunches end and naps are over, so don't fret it if you're running late.
Park information is here, though that doesn't really do justice to this park. There's a play structure that's good for kids of most ages, a large sandbox, swings, 2 HUGE slides built into the sides of hills as well as a greenway, climbing area and picnic tables nearby.
Additionally, I've reached out to other parenting groups in the area to join us at this playgroup. Hopefully this will mean more kids in the 3-5 age range to play with.
