I've been reading posts about 2013 TrikeTalk Rally VI. Eureka Springs is a great place to hold a rally. My husband and I have been going to Eureka every year since 1998 for scooter rallies.
The Scooting the Ozarks, STO, Rally will be Sept. 12-15, 2012 in Eureka Springs, AR. Welcoming riders of all scooters, maxi to moped, modern and classic (and usually a couple "big bikes", too), this is a "riders rally", where the focus is rides and scooters. Join in twisty, scenic rides, poker run, show and shine, good food, vendors, and lots more scooter rally fun.
We have a section on the STO forum about Eureka Springs link. Hope you can join us at STO, and my husband and I may make it to the TrikeTalk rally next year, too.
