I just got an email from a friend that works for the UW Organ Procurement Organization. There are still spots available for the Trey Schwab golf outing at Northern Bay on June 30th, despite the registration deadline passing. Cost is $125/golfer or $500 for a foursome. There are some partial teams, so if you are a single or pair, they can match you up with a team.
IWB has an article on it too:

If you are interested in signing up, you can send me a Inbox message and I can get you set up.
