I'm buying binoculars this afternoon!
I'm in a bit of an unusual situation: I've been a hugely active member of a forum for riders of the Can Am Spyder (reverse trike) for years. I've seen all of the discussions in there countless times, so I've become "overconfident" with my knowledge base.
I've been in here a week, and am learning new stuff again! The experts always seem to jump in with good answers!
