Imlay City opens April 1st. Last year I could not get my BG until late April, like Coach said. YP will be avail right away, and they told me LMB MIGHT be avail next week, if not then the week after.
This year I am going with a few YP, a few RES if they have any, about 25 LMB, and some GSH for LMB forage. Coach my pond is the same size as yours, last year was the first year for my pond and I added 150 BG, 150 YP, and a bunch of fatheads with good results
