George, I was looking forward to catching Friday night's class, but something has come up that requires my attention elsewhere. I understand you'll be back in the bay area in the early spring and am marking the calendar for that.
For anybody in the area: I've only had a chance to visit Kayla Feder Sensei at Aikido of Berkeley (actually in Richmond now) once but was very impressed and had a wonderful evening of training. Everybody was very welcoming and fun to practice with. So don't be shy about checking out this seminar!
