I LOVE this place and I can't believe I had no clue it existed!
I recently went there to view the Milky Way and everyone from the volunteers to the experts to the other guests were nice, knowledgeable and so fun.
I was there on a date but I highly recommend going to one of their viewing nights for any reason. Date, family trip or just to do something different, Rothney Astrophysical Observatory was a quirky, educational and all out fun time!
The only thing I'll say is bring bug spray and a warm blanket!
