This is not really about construction, but however (i also don't like to call Manitoba a prairie province, a very very small part of it is prairie and there is a big coast...), which are the best outdoor opportunities few hours drive from Winnipeg, Regina, Saskatoon, Calgary and Edmonton?
I think Winnipeg is blessed with so many things: two big wonderful lakes (Winnipeg and Manitoba), with beaches and parks (Hecla-Grindstone must be beautiful) and bird-watching in Lake Manitoba, a desert (Spruce Woods), Sandilands, Whiteshell (all those petroforms... kinda magic), Living Prairie Museum and Fort Whyte inside the city (that's amazing), Birds Hill, Oak Hammock Marsh (I want to go there so badly), Lake of the Woods is not too far (i love that name, it's so inspiring, mysterious
), Pembina Valley (that shouldn't be flat!). I especially loved Spruce Woods: the old house of the famous family (which I just can't recall the surname), and also in the way back i took a small road kinda parallel to the Trans-Canada which I found very very cute, all rolling gently, a lot of bends, many woods and meadows between fields. I also liked the small town of Neepawa, but that's way farer... didn't like Portage la Prairie at all instead, and the Trans-Canada, so boring.
