We knew about it, kind of planned to go.
But where in the heck do you park there when there is an event??

There is a new parking lot there now.

I bought a used copy of his "Gardening with Native Plants of the Pacific Northwest" off of Amazon a few years ago. It turned out to be autographed and had lecture notes from a seminar he gave. Nice bonus.

For pictures of the lights (opens for me without signing in to Facebook)...

Here is a link that might be useful: KBG Page

No idea why starting yesterday I can't open either of the links I posted here.

Using a different browser was the answer. Anyway, a subsequent page sent out by the garden said they got something like 1500 people coming to see the lights.
