A fly in hunt will be exponentially better than hunting from the road. Do your homework and find a good flying service and hunt in August. A DIY hunt is the way to go, twords the end of
August the meat is excellent and the antlers are in velvet but the velvet can be striped off and you'll have a nice trophy. Bring a good gun for bear protection ( VERY unlikely you'll need it )
You will be more than glad if you use a flying service, you'll get away from the crowds ( plenty of that on the road ) and see some of the most magical country on this planet.
Any of the services mentioned here are good ones. Another,that I have worked with ( guiding ) is Ovis Outfitters and Guiding
( Matt Thoft ) and I have praise for his area, ethics, flying skills , success ratio and for him personally.
Book early, they all fill up fast for the coming year(s)
Good luck!
