I know that many of us still have some snow on the ground, but I thought I would point out that one thing I like to do before making my first cut of the year (bush hog or mowing) is to have a modified version of the old "rock party". That is, I like to walk the yard and slowly drive the fields looking for left behind objects (usually by the kids or their friends):
--Footballs
--Basketballs
--Golf clubs
--Tools
--Sleds
--Arrows
--Rocks
--???
During the non-snow months, I make it a habit to pick up the yard every evening (I hate a cluttered yard!). However, during the snow months it's difficult to see everything that has been dragged out. I would hate to hit something while mowing.
