I'm a mouth call nut so I usually leave my friction calls at camp on wet days. With that being said you can use a plastic bag, put em under your foul weather gear, etc. etc.Another condition besides rain you'll have to contend with that willruin your morning is fog and it usually happens on one of those morning when your driving to your spot and the stars are shining and then as you get closer to the ol swampyour metwith a wall of the crap.Fog sucks!!
