For many, March Madness is a period of time when collegiate basketball dukes it out for top honors. Where mascots are plastered all over ESPN and the pools at work are in full swing. But for others like me, "March Madness" means a size#14 mayfly that rings in the spring season by bringing those early risers to the surface. While not the first hatch, it's the first real identifiable hatch that sends both novice and longtime fly fishermen yelling as if they were Paul Revere, declaring the March Brown hatch to have arrived on their waters.
