[tomislacker]

The city has something called Project Clean & Green that we could parse out. Example return content (ampersands are not properly escaped):

 <h2>Clean & Green week:</h2>
 Your 2017 Clean & Green pickup is on your garbage collection day during the week of <strong>May 2nd - May 6th</strong>. More information about the Clean &amp; Green program    can be found at <a href='http://www.city.milwaukee.gov/mpw/divisions/operations/environmental/ProjectCleanAndGreen.htm'>The Clean & Green info page</a>.<br/><br/>
