Yes, Dundee MI is where you want to go.
About 45 minutes south of Detroit.
It's just off Hwy 23 @ Hwy 50(?) IIRC, a few minutes west of I-75.
Bass Pro, Gander Mountain & the like can't hold a candle to Cabela's.
Been to them all, including LL Bean & Orvis, as well as a few others.
If you can, take in the Waterfowl festival at the Pte Mouille (MI) State Waterfowl area next fall. Loads of good duck-gear there too ... usually end of September,so it's already gone-by for this year.
