I’d have to think that there is not much difference between Silverman and a 1-0-1, so in the interest of NOT doing the same thing over and over, one would want to experience something totally different for their second long course event (i.e. the Mdot).
What are you kidding me? The Silverman course is a cut above any IMNA race in terms of the course itself. Then factor in all the incidentals (kick ass pre and post race meals, HUGE swag, and really cool location), Silverman is uniue unto itself. As are the 101 races.
