college basketball tournament is trademarked but Marsh Madness is not.
#WaterYear loves this time of year, with everyone talking about Marsh Madness (thanks to @neorsd.org for the pun). One big difference is that with Marsh Madness, you really should avoid filling in pools (A marshy pool in the Great Plains of Montana)
