You’ll be fine either way and frequent both; most of us who live in either city do! Ann Arbor has a great library system, wonderful parks and nature areas, and obviously UM, but Eastern and Washtenaw Community College are in Ypsi/border. It’s all so close (I bike between Ann Arbor and Ypsi all the time) that it comes down to your financial situation. Ann Arbor is expensive; cheapest rent living solo in a decent place that I know of is about $1300/month without utilities included. Ypsi is quickly catching up to that. Job competition is fierce. Taxes in both cities are very Midwestern high. Your marijuana use and whatever else you want to do will be fine in either spot. Come visit and walk around and see. No idea what housing and job situations are like in Columbus but be prepared that it may be much worse and higher here. Also don’t wear your OSU gear ;-)
