What to do for the last weekend of April?

Well, I need to be out of the townhouse starting April 29th, so either I can find some accomodations in town or look around outside of it. Given that I still haven't confirmed accomodations for May and onwards, I don't really want to book a flight back to BC for that weekend in case it turns out that I need to be in town then. That leaves either staying in town or visiting some place within driving distance.

Currently I'm debating heading to Cypress Hills Interprovincial Park, which straddles the Alberta/Saskatchewan border, for that weekend. Not everything is open until mid-May, but it might still be interesting to poke around there. Failing that, well ... err ... the town of Maple Creek, about 30 km North of there, was established during the construction of the CPR.
