Can we talk about picking responsibly?

I was leaving my normal stomping grounds when this guy with a tiny sack of mushrooms asked me if I had any luck. I told him that I saw a few but none big enough to pick. The guy proceeds to laugh at me and pull out his sack of probably 30 inch and a half tall morels. He insisted that's all the bigger they get. I tried to explain to him that picking morels before they reach maturity is like getting a deer license and killing all the fawns. He called me a unpleasent name that starts with a B and walked away.

Please, pick responsibly and let them fully mature.
