I'm going to try to post a few parks before my next bout of work travel hits. I'll start with Portland's Bayside Park. There's not a lot of documentation for it--some interior shots that are too tight to get much of anything, a couple of exterior shots, and an aerial of the field when it was used for amateurs after the grandstand came down. I didn't find it on any insurance (or other) maps. But I think it came out OK anyhow.

Here's an article about the stadium from a Portland history blog
A mix of historical and model photos are below, per usual practice!
