"Plan B is to partridge hunt in Central Square if the weather is still too warm."
Reminds me of my 1st. upland hunt in NY, many moons ago. We were driving along and saw a nice cover. Stopped to ask the farmer if we could hunt grouse. The farmer said yes, we can hunt "but not too many grouse around here, lots of partridges though".
Sorry I can't give you a personal waterfowl report. A few buddies have been out for grouse, good reports in general, although still many leaves on and the weather is so warm.
