We had a 1/2 inch dusting on April 20th, and temps went back down to 32-35 at night for a few nights. Might just have been enough cold weather to kill the Morel crop in my area this year. You wait all year, to look for something that only comes up for 3 weeks, and it only takes 2 days / nights of cold to ruin it all. It just isn't nice. Maybe it will bounce back. We still have about 2 weeks of our season left.
