title: Bad Request from Yelp API
body: <p>Inspired by <a href="https://github.com/Yelp/yelp-api/blob/master/v2/python/sample.py">this Yelp tutorial</a>, I created a script to search for all gyms in a given city. I tweaked the script with <a href="http://www.mfumagalli.com/wp/portfolio/nycbars/">these updates</a> in order to return ALL gyms, not just the first 20. You can find the gist <a href="https://gist.github.com/anonymous/42ffdf5deccde0746fd1">here</a>. The SEARCH_LIMIT is 20.</p>
  
  <p>I'm encountering a Bad Request error. I followed the Yelp Tutorial pretty closely, and am unsure of what it can be coming from -- I'm pretty sure the request is properly encoded, and all my API keys are right.</p>
  
  <p>The print out is below:</p>
