Yes definately take a quick scout (leave no scent). It will be quite obvious where the great majority of deer are crossing but look for a couple possible smaller less obvious crossings nearby also. Nice thing about corn is that even the slightest wind can make the stalks pretty noisy to cover any little sounds you might make.

One slight problem I have with corn is that although I don't get busted, the deer just seem to appear out of nowhere. One minute nothing- the next there's a deer standing there full body.

Good luck.
