Yannow... after thinking about it, I guess it's a little hard for me to choose. Spring was my favorite in the past, because I did love the rainy season back in Colorado (where I used to live and it wasn't as Humid), and because of my Birthday, back then I also enjoyed Winter because of the snow.
However, nowadays, I guess it would have to be a mix of Fall and Winter now. Fall because it starts to get nice and cold (and in the past it had Marching Season... it doesn't now), and Winter is a time when it's finally nice enough out where you can go outside and take a walk without dying of heat (because I live in Florida). Spring kind of dropped from the list, sadly, because of the fact that it started to become hot again, and I'd rather pack on layers of clothing, then have to were a minimal amount of it in order to try to stay cool. Yeah. XD;
Soooo... dr;tl, nowadays I like Winter/Fall because it's cooler, rather than the blazing how humid season of Summer, and the Spring before it here in Florida.
