Also to answer Rae's question regarding where to find morels around Duluth, take everything you know about finding yellow morels in the cities and throw it out the window. I've personally never picked around Duluth, but I believe it's similar to Bemidji - yellows are very few and very far in between, so you're much better off focusing on black morels. Black morels tend to prefer poplar trees. I've had my best luck in poplar stands with smaller trees (pop can to paint can trunk size) and lots of decaying leaf litter. I've also found a few under cedar trees though. I hope this helps!
