Start with your maps by looking at lakes and scouting those areas first. It's a good way to familiarize yourself with moose sign. There will be innumerable piles of moose dung on south slopes and roads but that is all from winter range so don't fall for it.
Get into marshy aspen and alder areas. Get over there a couple times if at all possible before season. It will make it much less frustrating if you already have areas mapped out. If you get stuck, ask for help.
