Living in Texas has flipped this question on its head for me. Although I still have the instinct and feel the pressure to make the most of a fleeting summer, summer is the new winter. You mostly stay inside and ride it out. Spring is actually awesome, all two weeks of it, unlike that disgusting few months of frozen mud we called Spring in WNY. Fall is like the peak of WNY summer down here which is great except the amazing weather lines up with a busier time of year work wise. Winter is typically a non-event, save for the occasional national emergency if we get a millimeter of snow. I'm gonna say September.
