Dave was honored to be invited by Geary Schindel to be the guest speaker at an installment of the Edwards Aquifer Brown Bag Lunch series.  In addition to presenting about CaveSim’s educational activities, Dave and CaveSim staff member Mary Hicks brought CaveSim to the Edwards Aquifer Authority for staff and visitors to explore.  Despite the rain, we had about twenty folks explore the cave during their lunch break.  A big thank-you to Alf Hawkins for taking the pictures below and allowing us to share them with you!
