Baby gate (Denver)

Hey guys I'm in need of a baby gate to keep my room mates dog out of my room... unfortunately my room doesn't have a door at the moment from before I got here so I just have a curtain up and the dog seems to like pooping in here when I'm gone and it's driving me nuts....if anyone has one they don't need please let me know. I'm limited to rtd routes at the moment so if it's not far I can go get it or I can meet at the green remedy dispensary on s.quebec way in Denver. Thanks neighbors!
