I'm strictly ATTGATT no matter the weather and I have been since my parents allowed me to buy my first bike at 16yo.
They said sure, but there's gonna be some rules. ATTGATT was one of them, fullface helmet and all, and it has stuck ever since. (Thanks Mom, and Happy Mothers Day!
I remember years ago when I worked at the local racetrack contractors showed up to repaint the lines in the 'motorcycle only' parking lot and all us motorcycle riders were asked to move our bikes to another parking lot on the other side of the track. I went out in my work clothes to move my bike and boy did I ever feel naked and vunerable!
