Here are some fun activities for you to do when you are on a budget:
My sister, brother-in-law, and I just visited Indeed Brewery. Although the tour guide wasn't extremely charismatic, because he was under the weather, we got an ample amount of beer samples and great service at the bar. It was probably one of the easier breweries to sign up for. You can also try Summit Brewery and Fulton as well. Fulton you have to sign up for the tour the day of. You cannot sign up for the tour ahead of time, which I found particular aggravating since it's based on first come first serve. But I can't complain to much since it's free!
2. Hear live bands perform for free at the 311 Club. There's never a cover charge and a great variety of music!
3. Watch movies in the park for free. This past summer my friend and I watched "Back to the Future" at a park near by to us. You can see which movies are coming up through Vita.mn or City Pages. It's so much fun! Make an event out of it and pack a picnic as well. There are a lot of people with dogs and their children. Get there early so you can get a prime spot to watch the movie. Be sure to wear some bug spray as well and bring a blanket or some lawn chairs to sit on.
4. Do something inside which is fun and educational by taking a tour at the Minneapolis Institute of Art. The free tours are typically on Tuesday and Thursdays.
5. Watch comedians perform for free at ACME Comedy Club on Open Mic night. You might be a little wary since comedy is a hit and miss depending on the comedian but these comedians are actually pretty good. If they aren't you saved on the show, so grab yourself a drink!
Hope these suggestions helped you get out into the city without breaking the bank. Let me know any other suggestions you have!
