I might travel 210 mile to minneapolis to do some speed dating. Is this to far away to find a girl friend.?

I believe that 210 miles will be fine if you want a long distance relationship, but in reality unless you plan on making that trip often that will not be the trip for you. If you want a long relationship that will can help you to learn more about the other party before any serious commitment is made, but again unless you plan on moving closer to Minneapolis I would advise against this plan.
