Join us for this month’s MASI meeting, this Thursday 5/21 at 7:30. We will once again be hosting our member's only fishy bucks event, where work done for the club (including meeting attendance) has earned you points, which become "bucks," which can be used to bid on fish.

New people can become members at this meeting and get fishy bucks just for attending!

This is a way in which MASI thanks its volunteers. Points are earned throughout the year by running fish at auction, serving in a position, writing Darter articles, giving a talk, helping setup for events, etc. You even get points just for meeting attendance.
