I'm chalking it up to weather. This winter had been rough in areas not usually used to rough winters.
I guess thats true as well, I know that I get a little burnt out when I can take the bikes out and hit up the usual spots. its not snowy here anymore just really wet and muddy, doesent bode well with 4x2 quads too well.
modify: That or people are starting to figure out that their not getting as much back as they thought they would from their taxes.
