I've finally heard back from the Port of Portland on the property adjacent to Costco in Hillsboro. Here's a link to see it on a map (

They said they'd look into letting HPR use it for a disc golf course and that they'd get back to us before Feb 1! They asked questions about cutting trees down. I said it would probably be necessary, but I'd back off of that if it meant not having a course there. They also mentioned aviation restrictions and not being able to put any structures on the property. I'll update here and on my web site (
http://discspindoctor.org/news.html) when I hear back from them.
