My momma always says Ludicrous is as ludicrous does!!! Justifying my position would be fruitless when consensus is, regrettably, unattainable. Only went the other way in order to counter the effects of the "other" side. Atv's don't kill elk, guns do! (???)
Cache.....go and enjoy! Proper preperation and proper attitude will prevail.
Best single advice I have ever received about elk hunting you probably are already aware of as a deer hunter......
Take notice and play the wind....always!
Especially when trying to slip up behind a herd of elk on your Polaris 600!!! O sure, the "Stealth" exhaust device will quieten you down considerably, but those elk can smell gas fumes for miles. So make sure you ride into them from down wind!!!!
Good luck and report back when you have made your choice/trek/etc.....
