Photo sequence reads from right to left. Taken during the daily 2:30pm polar bear feeding. Bear dived several times - then would climb back up because keeper threw fish in upper pool. Lots of fun. Due to huge crowd, I had a spot behind a rock where I actually could not see the dive. I just prefocused my camera and set a manual exposure setting, with the lens at wide angle, and held it above my head - firing in the general direction in multi-burst mode.
