My routine goes something like this.
Stop truck wait about 20 to 30 minutes. Play a game on the phone just let everything calm down.
Get out let out a howl to see if anything is around close. Wait a minute or two for a response. If nothing setup in the area I was going to go anyway. If I hear something adjust accordingly.
Careful with slamming of doors and rattling of gear as much as possible.
Setup try to get the call cross wind from me so I can see upwind, downwind and the other side of the call as best as I can.
Wait a few minutes after I setup and blow a hand call or two for 5 to 10 minutes or as much as I can, (I am fat and old).
Wait a little longer maybe 2 or 3 minutes and then play on 3/4 volume whatever sound I like for probably another 10 minutes.
If nothing switch it up for another 10 minutes.
If still nothing sit back and enjoy the day. Better then heading in and watching TV.
I hope that helps and take what I say with a grain of salt, do your own thing and have fun. It ain't serious business and shouldn't be. Best of luck to you and if you get something be sure to post pictures.
