So even though I haven't added anything here for a while, I still have been pondering next year.
A couple new thoughts:
Given the decline in participation should we consider adding another owner's group? Personally I was thinking about the Naked Goldwing (NGW) group. There are several SOHC members that are also members there including me, Terry in Australia, and Old School Is Cool from Michigan and the GoldWing is a common 'other bike' here at SOHC4. I'm going to be riding mine for the Michigan leg of the Rally since my 550 isn't close to ready. I think the NGW members would be interested and help keep things rolling along.
There have been a few suggested formats: (1) staying with the current style, (2) a ride-in type event (think the Wingding events that the GoldWing Riders Association has hosted for 20+ yeares), and (3) my idea of shipping GZ around so he can represent the SOHC at the various special events that happen around the country.
Right now there are actually 3 GZ's: his year's Pimpzilla, Lefty from v2.0 and the original from the 2011 inaugural event.
So really there is no reason why we can't implement something like my idea and still also do a Relay Rally 4.0. Create a couple more banners and let our colors fly at Mods vs Rockers Dallas, Chicago, Indy, etc., Rockerbox, Mid Ohio, Barber.
