True enough.This hobby seems very "follow the leader" to me, in that it seems like everyone comes up with a group consensus and then drives what is "hot" based on that. For example, everyone seems goo goo ga ga over bounce mushrooms, but they really do nothing for me.
So once you start seeing a bunch of people doing one thing, it somehow becomes "the next big thing." I'm sure clams will have their day again.
But you do see more clams on the market in spring and early summer.
But you're right that to a large extent the newer hobbyist drive the demand.
