Go to Midwest and ask around. I'm from Northwest sub but I can never keep enough beer to swap. I got into the hobby to tinker with recipes and have something to drink. Which means that I am usually out of beer, lol.
If you are buying supplies, kits, anything at Midwest or Northern you will get a 10% discount with your MHBA card. They also keep a calendar of local club activities.
You can also consider joining the St. Paul Home Brewers Club. We also get 10% off and there's always beer to share/trade at the monthly meetings, which are at the Happy Gnome.
How far northwest? I'm in north MPLS near Robbinsdale, which is technically NW Minneapolis! I'm not in any clubs either, mostly cuz I have so many time commitments I can't imagine adding Another meeting LOL.
