On a related note, if you're ever in Seattle and enjoy these types of things, the Northwest African American Museum (naamnw.org) is worth checking out, and it's right next to the just-renovated Jimi Hendrix Park, since he grew up in the general area it's located in.

Judkins Park across the street (23rd Ave), or walking east towards the pedestrian/bike path along the I-90 floating bridge (Sam Smith Park), are also worth checking out! Especially biking across the bridge over Lake WA.
