Excellent idea happy wife happy life eh ! When I was married and living in Windsor and Lansing at the same time the rate was between $1.40 to $1.50 to buy US with Cdn but Casino Windsor was buying US at $1.65 wife and I used to take turns running in with a few hundred at a time US cash then run to the Royal Bank on Oullette at buy for the rate then run back again LOL . We could get 2 or 3 trips each in before security would say enough , we'd make 4-5 hundred Cdn by then and enjoy a free weekend at a hotel with room service . Paid for her trips 2 or 3 times a month for like 4 years that way .
