  • April through August at the Illinois River Watershed Partnership Learning Center, 219 S Main St, Cave Springs, AR 72718;
  • Otherwise at Gearhart (formerly Ozark) Hall at the University of Arkansas, Fayetteville, Room 17;
  • See Membership Announcements for any changes in the meeting locations and time, including those related to pandemics or epidemics.

Membership dues are $10.00 per year, with discounts for multiple members from the same household.
