This evening (03/01/10) the JMMRT hosted Marc\'s new lecture, and let me tell you, as with anything Marc does, this was GREAT! It is a mixture of some old, mostly new, but all doable commercial magic that will have you adding to your repertoire and blowing some minds.
If you can go to one of Marc\'s lectures, DO IT! If there is not one near you, call him and get your club / group to schedule one. You will NOT be sorry.
