Yeah, the top is a cover of sorts... Like a golf umbrella like you mentioned. The thing is that when we get really hard rains that are blowing sideways, it travels up the canopy and gets into the vented area. Drips water all over everything... Like our race team haulers on our semis - they don't have a single vent area for this reason as it will cause leaks under heavy rains and that is a no go when it is time to be working on bikes with exposed parts like carbs, intake ports, etc exposed... Know what I mean, Vern?
