When I was in my early 20's it was byfar my favorite season. The days were shorter, which gave me longer nights and I wore my pimp sweaters because I do not like wearing jackets but of course no sweaters now...I would look like a bear walking around.
Even though I am no where near in my 20's now, I still rate fall as the best season..great sleeping weather, all four major sports are playing, Thanksgiving with 4 days off, leading into Christmas and if it planned right 2 weeks off.....it is the perfect season when winding down the year.
Spring is rated #2, I would rate Summer higher but I do not like sweaty testes. Winter would be perfect but it snows, I can deal with the cold but keep the snow...I am no longer a kid and don't find it fun to play in.
