Markwest Energy Partners is a midstream Natural Gas Pipeline outfit. Roughly 2/3 of their operating income stems from the Marcellus / Utica / Northeast regions, with the remaining third from the Texas / Oklahoma area.

I bought in in April 2012 at $58.60, sold some in May 2013 at $67.12 to fund other purchases, and it's currently (December 2013) sitting at $64.11. The 52 week range has been between $49 - $75, and the current yield is 5.3%. I originally bought it with capital appreciation in mind in addition to the stable distributions.
