When you talk with them, I would suggest running through a detailed list so that you can confirm what they cover for that cost, and what they don't cover (all of these costs can add up and bite you pretty fast). Among this I would check if covered:
- Transport of meat, antlers, and cape from the field to McGrath
- Handling/storage of your meat and antlers in McGrath
- Total weight allowance per type of aircraft they fly (this is the total weight YOU are allowed, not the total payload of the aircraft)
- Expediting your meat/antlers/cape for transport to Anchorage and/or beyond
- Any gear provided by them, or you responsible for bringing all of your own gear
- Moving you to a new location if the location you are dropped is devoid of animals
Other questions I would ask:
- What type of accommodations are available if weather keeps you stick in McGrath for 1 or more days before flying into the field
- If they don't help with meat/antler/cape in McGrath, what type of facilities (tent, cooled shed, freezer space, etc.) might be available for you to use/rent
- How do people typically ship their meat/antlers from McGrath to Anchorage or Fairbanks
Good luck!
