I considered posting this elsewhere, but only Canadians are really going to get why it's funny. Regina being totally self aware about it's (lack of) reputation made it for me.
Not a local, but as someone who joked "We could go to Regina! There's..." and trailed off as I saw stuff on Google Maps, here's some suggestions:
-The Regina Floral Conservatory.
-The Mackenzie Art Gallery
-The RCMP Heritage Centre
-Government House
-Royal Saskatchewan Museum
There's some other stuff too, particularly if you're willing to drive out of town. Enough to make me go "Huh, that could be mildly fun/interesting".
When asked for comment on its lack of tourism resources, the City responded, “we made a tourism video in the 90s. I don’t understand what else you’re expecting.”
