I believe in the Necklace of Death...So I carry about 8 to 10 calls around my neck..
I do like to go to Army & Navy stores or Waterfowl areas of stores and buy their bags to carry a little bit of everything I might need on stand.
The paratrooper type gear bags are nice to carry and they can take a beating...I don't like the kind you carry on your back..I like the kind you carry on your side with a shoulder strap..
Mask & Gloves for daytime calling, rubber gloves, small kitchen garbage bag with ties for fox..Flea killer to spray into that bag and seal it up..This remains in the vehicle of course..
I also carry extra gear in a large Homedepot or equal too tool box..Lights, batteries, nightstyks, extra Crit-R-Call call,
Good gift to get a tool box..You can make one up for all of your hunting you do.. One for deer, one for predators, one for chucks, one for black powder, etc etc etc...When it's time to hunt just grab it and go...Make sure you look inside so you take the correct tool box...
