This is not an April fool's joke---

Yesterday afternoon I was at the north end of the arboretum (actually the
big grassy area that borders the lake, between 520 and the Lake Washington
Blvd. onramp to 520) exercising my dog, and well, a harbor seal
jumped out of the water.

I watched it for the next hour or so. It only
appeared when a dog was in the water retrieving sticks, and I hate to
anthropomorphize, but it seemed to want to play with the dogs. After it
goosed him in the water, my dog wouldn't go back in, but other dogs
weren't at all bothered by the seal. When you threw the stick, the seal
would surface where the stick landed in the water, and as the dog
approached the seal would sink down. Once the dog had grabbed the stick,
the seal would goose the dog, then make a couple of leaps out of the water
from along side the dog as the dog swam back to shore.

Have seals been reported in Lake Washington before?
