I took my bike out today for my first ride ever.

I have not yet taken the course, and I know that some of you will be disappointed, find comfort in that I was wearing all my gear, and have been doing much research on how to ride safely....it was a very enjoyable time, gong up and down and around my block.
My heart was racing with excitement, which I think lead in part to my visor getting soaked with condensation. Boy did it suck having to stop and take care of that. What is the solution? I'm guessing I need to open the vents on this helmet and get some air flow, is this right?
Do I need to add micro fibre cloth to my list of things to have handy whilst on my machine??
