We visited an octopus farm - pretty interesting and unusual. I got sprayed and wrestled with a couple of lovely color-changing beasts and fed them some crab legs.
Walking on a large lava field and actually getting close to the flowing lava was amazing! The hardest drawing of the trip: so much change in the flow and colors, so little reference when you look at the landscape... and I wanted to stop and draw every ropey wrinkle of old lava on this hike!!!
