my camera & light aren't as good as ZIPP's but there was a cool sound that I barely captured. at one of the what I call "water crossings", there's a part of the park road that floods. there's some ice now, but it's not complete. so one has to ride thru some water. as I climbed onto the ice on the other side, I must have cracked it. this ice must be connected (due to the flooding) to the rest of the ice covering the estuary. this in turn, caused some kind of sound radiation, echo or low roar. it was fairly loud & spooky, at the moment. a weird deep, hollow moan. I can barely make it out at the :30 sec mark but I have to turn the volume up
