Yep Dead elms, Popular groves,Different contours of landscape.Spray yourselves good with perm juices or super deet. Wonder aimlessly through the woods. Think like a mushroom. Just pop up for know reason at all in the weirdest place. Being silly but these are some things to get you going. I've found a lot of blks up north by pine trees for no ryme or reason. You have time to research before they pop there anyway so search away. Good luck!
