I finally feel physically and mentally recovered enough to handle whatever comes, so today I rode Lance outside our arena. We warmed up and schooled in the arena first, then rode down the lane to get the mail. The vineyard was playing the distressed deer bellow from speakers next to the road (I have no idea why; that's usually an autumn thing). Lance made it by okay on the way to the mailbox, but on the way home he got increasingly alarmed, in spite of lots of lateral work to keep his mind and body occupied. So I got off and led him away from home, then got back on to ride home. Again he got to a point where he seemed ready to "stop, lock, and load," so I repeated the dismount, lead away from home, remount, and ride home. The third time he was able to hold it together and we made it safely by the scary area. Success!
