I wish I knew a solution for this Cypress. It has been debated many times. We actually had more races in early March in Oregon a few years ago - the Banana Belt series was the first 3 weekends of March (and was cancelled on more than 1 occasion due to snow), and Dirty Circles used to be a series of 3 races on consecutive March weekends and is now just 1 race.
I remember getting muddier during a Heiser Farms circuit race than I ever did at a cross race. I think that was late February or early March. It was a P/1/2/3 race, so I had hella teammates there and we were all wearing baggy showers pass jackets to try and stay warm. It wasn't until we got into the team car that we realized that some of the mud was manure from one of the nearby fields.
