I grew up in Indiana. It's not exactly a tropical climate, but the cold weather sticks to December-February, then it's temperate until May or so, when the hot stuff sets in. I always relished the summers, except those few days in the 90s. When the fam moved to Colorado when I was 13, I hated the weather immediately... where we lived, it snowed 9 months out of the year. It's an interesting shock to the system... and it's no wonder I wanted to move to California as soon as I was old enough to get out of my folks' house. Denver's not bad, though... now that I can handle the cold.
