Located in the Detroit area, General Motors Heritage Center (GMHC) contains more than a century's worth of the Corporation's technological marvels and achievements—from automotive to diesel locomotive. It also houses millions of documents and records from every Division that GM's staff researchers reference when answering media outlet requests, such as HPP's.

A couple of weeks ago, I ventured eastward and found the collection more intriguing than imaginable. The Collection contains approximately 600 vehicles from all GM makes—including a number of one-off experimental prototypes. The main hall houses approximately 130 of them at any given time and the rest remain securely stored offsite, shuffled in regularly to keep the display fresh.

Unfortunately, GMHC is closed to the public, but arrangements can be made for group tours or event hosting in the main exhibition hall. Several months ago, the GMHC staff I've come to work so well with over the years graciously invited me in for a visit. Considering it an opportunity of a lifetime, I hoped to make immediate plans, but with winter's fierce grip on the Midwest, we decided it best to wait until spring.
