Greg - I just sent you the photos. If you post them to this thread I want everybody who sees them to know that the film has gotten quite a bit worse. Just to get some contrast in the photos, I introduced about 1 ounce of dishwashing liquid into a red-neck fountain I created just to break the stuff up a little. Had I not done that, the film was so uniform over the pond (no wind today to blow it to the side) you may not have been able to tell anything was there.
