Probably stating the obvious. Give your shotgun/s a good thorough cleaning. I store mine in one of those silicone impregnated gun socks in the gun safe.
My duck decoys are getting pretty beat up. In the past I have touched them up using decoy paint and brushes of various sizes. Just wondering if any of you have ever used one of those small air brushes? Seems like it may be faster, and once a guy gets the hang of it, produce better results.
Excellent tip on releasing the rubber thing.
FWIW, this past year I experimented a little bit. Even though most people say that using a "Texas Rig" on your decoys is only good if your hunting really shallow water, 2-3 feet, I decided to give it a whirl using 6-7 foot lines. I rigged up a couple dozen just for grins. Worked pretty well. Definitely a lot quicker setting and picking them up. The long lines were kind of a pain at first but then I read a tip on a different forum. The guy was using a piece of black 2" PVC, he would retrieve the decoys and put 8-12 decoys on a caribiner and then once he got to the boat he would take the caribiner off and push all of the lines through the PVC and then re- hook the caribiner. That way the lines are all in the PVC pipe and not getting tangled up with other decoys. I used 5' lengths of PVC and it worked really well. I think that much longer than 6-7 feet and you would just be fighting it.
