I agree, yet disagree. The same logic that makes me believe it will crash is what also could lead for it to triple again. Even if future promises don't work out, there's a lot of potential and that's why it's surging. It's okay to pull out and buy things you enjoy, but I certainly wouldn't pull out extra and have it sit in a low interest bank.
P.S. Thanks for sharing the green egg, never heard of it before. I've had a gas grill for 3 years now, but still struggle with timing. Hope some day I would be good enough to want/need one of those grills.
