Andres,
The current forecast is a 20-30% chance of "showers" Sat. So that also means a 70-80% chance there won't be showers. (showers are more isolated & quick and can be anywhere in the general area, rain is more constant and is not in this forecast)
We have just about 15-20 cars (hard to tell some folks sent their signup in directly to Wheels & Waves). The plan is IF the forecast changes negitively (like 60% chance of RAIN not showers) then we will still go but in our weatherized vehicles.
Thanks,
Mike
