Cinco de Mayo and Fiesta are both great reasons to leave town! I'm talking about Syncro de Mayo, as VW syncro vanagons.

We have this event every year at Hollister Hills SRVA on the first weekend in May. This year is our 10th event and I'm the person organizing the event so it's a must do for me. The event is 4 days long and we usually get about 75 vans or so. We even have folks come from Europe.
Here's some video of last year
THat's an obsticle coarse with PVC poles that have golf balls balanced on them, if you hit the pole the ball falls off and you get penalized. We are talking about a new driving contest this year with blindfolded drivers and a navigator giving instructions. Should be fun.
I still hope to make it to Moab but I'm allready taking of a week in febuary for death valley trip, 2 weeks in march for a trip to Europe and then the last week in april for SDM and Overland Expo. Shaping up to be a very busy spring!
