Here are a few things I look for when going out of state;
1) Do you need a ORV sticker for an ATV/UTV? Wyoming yes.
2) Do you need any special stamps, etc. besides your license and tag? In Wyoming you need a conservation license & additional archery license/stamp if bowhunting.
3) Hunter orange requirements? WY yes.
4) Tagging requirements (i.e. on carcass or antlers, etc)
5) Evidence of sex requirements
6) Edible meat definition (i.e. Rib and neck meat in addition to quarters, backstraps, and tenderloins? )
7) Legal weapon definition especially if hunting with bow or muzzleloader (i.e. Fixed or mechanical broadheads legal, sabots, pelletized powder legal, copper required, etc)
8) Antler point restrictions/definition of legal animal for the tag you are hunting
9) Regulations concerning hunting or camping on state land (blue shaded land on maps)
10) Are you allowed to take vehichles off-road for game retrieval?
11) Review NF MVUMaps to see what roads are open and closed and where dispersed camping is allowed along open roads
12) Laws or regulations concerning minimum distance you must camp from water sources
13) Know and mark your hunt unit boundaries on a map and always know where you are when hunting in relation to unit boundaries (a GPS with the landowner chip is invaluable IMO) or buy a map that has the unit boundaries outlined.
14) Review the trespass laws for the state. I do my best to avoid all private land but it is good to know the law just in case (i.e. is corner hopping legal?)
15) If bowhunting can you have a firearm in your possession?
16) Laws concerning the use of scents/baits
17) Do you need to have a hunter safety card in your possession while hunting?
There are always a few quirky regulations you need to watch out for in some states (i.e. CO) but most regulations are pretty similar from state to state with just a few tweaks here and there...
Have fun and good luck!
