No Morels in SE Pa

Four weekends in a row of going out to a few very proven spots over the years and have not even found a half free let alone a real morel mushroom. Im very frustrated. Some years i find patches so big im afraid to walk because i dont want to step on any. Other years i have to work very hard to get a good batch. This year, nothing, ziltch, natta one. I couldnt feed a chipmonk. Is it the crazy weather? Idk! Does anyone have any insite on this topic.ive been hunting morels for about ten years now. And when you finally think you have them figured out, papow! They do something else.
