Ignore the comments about the mosquitos being large, they are just bothersome, and black flies - they are gone when the hot weather hits, and we can get plenty of hot weather in July and August often in the eighties and into the nineties sometimes
Birds Hill Provincial Park is not the greatest for camping but if you want to explore the sights of Winnipeg, great museum, lots of history, Lower Fort Garry, the park is just north of the city.
Riding Mountain National Park is further away but beautiful, earlier this month Clear Lake there froze solid without any snow on it a few weeks ago and you could skate for miles. Of course you won't be doing that in the summer
We would be glad to show you the sites, we are not far from Winnipeg, in fact we are right at the border at the end of I29, cross the border and you are in our town, you'd be welcome to boondock chez nous! Just PM me if interested.
p.s. last January we enjoyed a visit to Omaha, your zoo is wonderful! We are through Council Bluffs regularly as our daughter and granddaughter are at Fort Leavenworth.
