September late -get it out of the way, it's still warm, and we are still tan!
October early -pretty fall colors and hopefully not too cold
October late -plenty of time to get my cards ordered early to get a deal
November early -I've just started to enter the holiday spirit, hopefully there will be a little snow, just in time for black friday
November late-I don't focus on holiday stuff until this point anyway, and it will hopefully look more snowy out!
