Left the house (on the bike of course) at 9:30 this morning and it was 66. Went through the front between Parker and Lone Tree, by the time I got to my destination at 10:15 it was 54. When I left to go home at 11:30 it was 34. By the time I got home it was 30. 36 degree drop in less than 3 hrs. Now about 2 hours later it is 19 and I see a couple snow flakes
