Just curious, why are you looking into a drop camp?If you want toDIY then "DIY"! Don't takethiswrong but you are starting early enoughin the planning process that with some diligent research,you could hunt elk far cheaper than the dollar amount you just proposed.What physical shape are you and your dad in?Are you planning a rifle hunt, or a bow hunt, or blackpowder? Colorado has otc rifle and archery permits for non-residents in certain GMU's. If you're interested in Colorado, then start here;
http://wildlife.state.co.us/, there is a ton of information if you spend the time researching.
One thing to remember about a drop camp. If an outfitter has fully guided hunters willing to pay full price plus tips, why would he drop a couple of DIY hunters into a prime area full of game? I would seriously consider either a fully guided hunt, or an exclusively DIY hunt! There are plenty of people on this site willing to help you out if you're willing to put forth some research effort. Good luck!
