1. Why would you go anywhere without one ?
2.You know exactly , no ball park maybe's .
Sort of like the MMI data no Jounal page on that . No discussion of the unusual high values . If you did not know Barry before hand the average guy would walk away from this like they might from a SARS patient . Sort of like sitting Bobby Orr on the bench in the 7 th game .
But unfortunately some would use the knowledge to their advantage . So we wait .
