Our association offered a three day Natural History of the Sierra Nevada with Jack Laws and David Lucas- a naturalist's dream team. I tagged along for a few sessions, and had a delightful time peering at insects, looking under rocks, and picking up sketching tips from Jack. Jack also offered a nighttime astronomy viewing and we all lay huddled against the cold in Tuolumne Meadows gazing at the Milky Way.
A personal highlight--on our way down to the Mobil Station for dinner one night, Jack made me stop the car so we could help pollinate some evening primrose on the side of the road.
