Well i just saw that someone brought up the spring checklist post and maybe this would be a good place to put a fall checklist post.

besides cleaning up the obvious gardens, garden tools and hoses here are a few things i think people should do.

clean chimney

change furnace filters

close your crawspace vents, leave attic open

winterize your small equipement, use stabil in your gas

prepare your shovels and snowblowers for winter snow

check over your winter clothing for repairs or cleaning

get your firewood in

do a final lawn mowing

rake up all leaves

protect your trees and shrubs from rodents

take in water features, drain well

clean and put out bird feeders

please add as i don't have a list here to reference from

also there are a few really great books out there that tell you what do to each season of the year
