Have you tried on line? Like Midway USA?
I’ve called around locally before heading to a store, like at the beginning of the pandemic to find out if what I wanted was there. Otherwise most of my shopping for things I don’t wear starts with Mack’s Prairie Wings and Rodgers Sporting Goods. I haven’t checked those two for rifle ammo though.
We bring a weather and an FM radio. Cell phone coverage is sporadic, but you can find a signal almost anywhere (but usually it originates from Canada).
Bad weather can come in a hurry, so it is nice to be able to know what is coming in advance.
I would agree with James about tough bite. The last few days have been tough. You wont see those mayflies in Big Bay, because they all hatched last week. We have had high heat no wind to go with mayflies,then fish flies so I think that explains the problem. It will get better soon as minnows become primary food source for eyes. Wont see you out there for a while as I have to leave for a week. Good Luck !!
