For as long as I remember we helped the deer out though winter with whole corn as a treat and alfalfa for good health. With our stupid laws they'll issue tickets for feeding them if someone turns ya in, I've only gotten 2 of them. We get a lot of snow here and usually the ground is froze so there are many like me that helps them out.
We've gone out and dropped trees so they could eat the buds. The past several years we've had logging done so there are plenty of tops for them to browse. (They can't ticket you for that as far as I know.)
