I don't shoot deer or eat the venison ver often simply because I don't like the taste. I do 'harvest' the occasional pheasant or turkey for the table. Yummy.
You will normally not find much edible meat on a road kill deer.
If you don't like the taste of deer meat it may be because who ever is preparing it for you doesn't know how to get the "gamey" taste out.
I can tell you if you find the right person who marinates it properly you will like it.
Deer sausage is good also.
Marinate it over night in vinegar is one way, beer another etc...
