Been to only one.
Went to Spyderfest this year. Pulled the bike down on our trailer. 15 miles outside of Springfield, our trany bit the dust. Days latter and $3200, we got the vehicle back with new trany.
Good thing we had the bike for transportation. Oh ya, Springfield got one of the worst rains spelling ever. Diehard riders were still out, but please, it's dangerous to ride in pouring rain, and you can't convince me it's fun. Stayed in hotel.
Only good riding day, we got some lights put on by TricLED, and hit the road. Got 10 miles outside Branson and bike went into limp mode. Crawled back to Pitbull who took pity on us and thru it on a computer. Electrical codes, so back to the vendor village to TricLED. They took a look, and rewired what they had added in the morning then off we went for a long ride, with no problems.
Next day rain, rain, rain. Drive home - Rain, Rain and more rain.
So what do I want to see in a Spyder event.....
Less rain, but hey, who can control that. so..
Vendor Village inside to stay dry.
More technical and practical seminars.
Tire dealer with choice of top tires for sale.
In interesting location.
Hotels and camping available.
Sign up board so attendees who come from a same area can network easier with riders near them, that may continue when they get back home.
