Can't get Google to Index .pdf in wp-content folder

[inboundauthority]

We created an indepth case study/survey for a legal client and can't get Google to crawl the PDF which is hosted on Wordpress in the wp-content folder. It is linked to heavily from nearly all pages of the site by a global sidebar. Am I missing something obvious as to why Google won't crawl this PDF? We can't get much value from it unless it gets indexed. Any help is greatly appreciated. Thanks!

Here is the PDF itself:

Here is the page it is linked from:

Egol,

Thank you for your advice and for your commendation. I really appreciated that. We worked hard on it and it is a fun niche to be in and lots of active and involved cyclists who appreciate this kind of piece. I will edit the properties of the document. I hadn't thought about that.  Thanks very much!

PDF documents can be stubborn to get into the index.  If you are hitting it with plenty of links, be patient.

This is a really classy document.  Very nice. Well done.

If this was my document I would edit the "properties" and give it a title tag that will enable it to compete in the SERPs a little better. There is also some blue underlined text in the document.  Where those supposed to be hyper links? they are not working for me.  However, I see that BillBoneBikeLaw.com in the last line of the document is a working hyperlink.  That will allow pagerank to flow back into the main site.

This is a "best on the web" document.  Nice work.

I really enjoyed reading the document.  I used to be a hard core biker.   I've been honked at, yelled at, cussed at, throwed at, spat at, and hit by both accident and intent.  A long time ago I won one of the age groups at The Great Floridian.  I still remember Sugarloaf and a mad dog attacking out of an orange grove on the downhill.
