Only in Seattle would someone do that! In the steamy south, we get under trees for shade and avoid the hell out of them when it rains - due to lightening. I have spent some time in Seattle and must say I really liked it despite occasional drizzle to near constant light precipitation. Not sure I ever heard thunder there come to think of it.

I have friends in Greenlake just FYI. Love skating the Burke-Gilman too, especially through campus then all the way to Redmond and back. Been up a few peaks near Rainer, some rock climbing south of town, and backpacking in the Cascades. Makes me wish I was under a tree there right now as it is 110°F in NOLA right now.
