I thought this was a very interesting comparison of the last few years. Clearly the setup this year has been MUCH more effective than in the past. The pipe hole stayed open, although small, all winter long minus three to five days it appeared semi closed up. All the other holes opened up about a month sooner than in the past. Trying to get my buddy up soon to get a DO reading. I am hoping that produces improved results as well. Pics are from either the same day each year or one day off.
