Looks like it may be Point Defiance...
Man, these Tacoma folks take awhile to get goin' in the morning. ;-)
Well, the zoo and probably the fort cost money, but the zoo is kinda cute, it's a small zoo, and the aquarium is really nicely done. And I think the walking trails are still good if that's what you're going for. A little early for the Rhodies - too bad, cuz they have a big rhodie garden. Lots of harbor seals and sea lions around Point Defiance. If any of the trails say they go to a viewpoint for them, take them up on it.
If you're going to the zoo and taking Cisco, there's probably places to park that are shady. It's not gonna be ~too~ warm today.
