I don't know if I told you this before or not, but my dad has found a way to plant Morels where you want them (granted, they still need favorable conditions). When he picks them, he transports them in a solid container (not a mushroom bag) that will catch any spores that fall, then he soaks them overnight in the fridge in plain water (not salt water as I have seen people suggest) and then he takes that water, with all of the spores in it, to where he wants them to grow and pours it out. He has actually gotten a decent crop of them in his front yard from doing that.
