Actually, there's no season that I hates.
Summer is so nice because it's so warm, sunny & green. I love it how you needn't to wear a LOTS of layers when you go out. I love all that living nature all around me.
Autumn is so nice because of that fresh & earthy air and wonderful autumn colors. I love the fresh shower of rain (except if it lastes during many days/I have to do lot of job outside).
Winter (my favorite) is so nice because of that white, virginal snow cover which covers everything under it. I love that whiteness all around me, I feel it lightens whole the earth. Oh yeah, and Christmas and my birthday
. Only it isn't nice if there's really cold outdoor or it's so warm that snow can't stay but turn into slush.
Spring is so nice because sunlight increases and the nature starts to living again.
Oh, now I feel I could almost write a poem
Good luck with the trail riding Walkamile. I cross my fingers for the weather.
