Make a donation to support the OBA Wintergrass Jam Suite
The OBA Wintergrass suite is much more than a party room. It's the one place in the largest, most populous bluegrass festival in the Northwest that attendees can get to know the OBA--our members and leadership, what we're up to, what we stand for--and we routinely have a surge in new and renewing memberships, not to mention volunteer signups as a direct result.
