mac87toy- Best advice I'd give you is get a helper who's a knowledgeable local who lives and breathes for spending his every fall and winter out hunting in those units.
The success rate in those units is high, but there's a very good reason that they give out so few tags....the moose population is very low, and they're widely scattered.
You don't want to just take a stab and guess where there "oughta be some moose" or start looking where someone "saw a moose one time". If you use that approach, you'll waste a lot of time spinning your wheels. Find yourself a deeply experienced, no-bullcrap local or two, and get down to business. Good luck to your wife!
