I have promised the kids a visit to Frost Park, but if you are out and about today around noon, stop by the Point Defiance Zoo & Aquarium to watch keepers distribute popsicles to the zoo's largest land animals. Should be lots of fun to watch.
The zoo's in a relatively cool spot where breezes come in off the Sound, also the water feature ought to be running in the kids zone. (Where you can finally see the meerkats! We stopped by a couple of weeks ago and they were very alert and inquisitive.)
If you snap a photo email it to me and I'll post it on the site: email@example.com.
