Cinnamon or Whole Wheat? Multi-Cache

This cache will take you on a short walk through a neighborhood containing a commercial bakery.  Depending on the day of week and/or time of day, different flavors of bread are being baked and the aromas waft through the air.

Note the calculations for Stage 2 have been reworked as of October 2, 2019.

The first stage will take you to the parking lot for the Fairview Train station in Downers Grove. Coordinates will lead you to a CORNER spot on the south end of the lot. What number parking space is that? Call that number AB. The parking spot directly north of AB is numbered CD.

Divide AB by 10 and add the result to the posted north coordinate. 

Multiply the value of (only) C by 70 to give you XXX. The new west coordinate will be N 087 59.XXX. 

The resulting coordinates will take you to the final which is a short distance away.  You will still be in the vicinity of the bakery and its captivating smell.
