Not a bad idea IMO, but might be hard to schedule. Most of our rallies are 2 weeks apart
I was not thinking that existing rallies would be re-scheduled (or re-located). Many people - myself included - plan their schedules well in advance based on anticipated events. (For example, Fly-by Week is typically late August - I met you there (or somewhere) while I was riding with a different group. Moving that date might screw-up someone who left some slack time in their vacation schedule for it based on historically anticipated date, if you know what I mean. I missed a Spring meet with another group this year because it was 3 weeks later than normal, and I had already made other plans. That hurts attendance.)
Rather, I would suggest planning a pre- or post event coupled to an existing rally.
For example, this year's Fall Colors is in Lewisburg WV. There are several locations within 1-day's ride (let's say 350 miles, e.g. Johnson City TN or Maggie Valley NC) where a mid-week meet could be scheduled. That allows someone who attends both to ride different areas at each meet, while allowing someone who can attend only one an opportunity to ride in an interesting locale.
Obviously would take some coordination. Schedule the existing weekend meet first, then add the new event.
Right now, I gotta believe existing event meet coordinators are hating me - deservedly so - I know how much effort goes into planning a simple weekend - I've planned several group meets and it is not as simple as it seems - I empathize with their concerns. So might allow the 2 different events to be planned by 2 different coordinators.
If this sounds like I'm volunteering; I might later next year. I'm very new to MSTA - I have no understanding of how this organization works - I apologize to anyone whose toes I might have inadvertently stepped-on.
