Hey NampaNewbie,
I'm also a Nampa guy. I have hunted the Marsing area a little. I was out in the Hardtrigger area last Friday. I had a hard time being quiet getting into the stand...rain put a nice 'CRUNCH' on top of the snow. I only made 2 stands, didn't call anything. Saw fair amount of tracks, driving between stands.
PM me if you want more info. I'm no expert, and I don't get out too often (family), but I LOVE calling coyotes!
