I've been looking a few hours a day for the last week in the KC, Kansas area and hadn't found anything till last night. The woods I've been looking in are full of dead elms and should be perfect some day soon, but I hadn't found a single one till I got out in the grass. I was about to give up and started walking across a grass covered hilltop about 50 yards square and started finding them all over. Some already so old that I either left them or they fell apart in my bag. I realized the hilltop had been thick woods at one time and it had been scalped to the ground leaving mostly elm tree stumps that were covered in grass. I was regularly finding 4 to 6 shrooms around the stumps. I determined because the hilltop was so heavily filled in dead elms and so well exposed to the sun on the hillside facing south that it allowed the shrooms to pop well before the shrooms in the trees. My advise till it gets warmer? Look in the grass. And if you've never tried morels, do so. THEY TASTE GOOOOOOOD! :)

That's the way it has been for me around Columbia. Big morels on the Missouri River bottoms (they warm up early) and small yellows and grays along the edges of clearings up on the hills. Nothing, yet, back in the deep timber.
