We report the first experimental measurements of the contact number distribution between
randomly packed granular right cylinders (rods and disks) as a function of aspect
ratio. The average coordination number 
for cylinders varies smoothly with aspect ratio rising from 
for aspect ratios close to one to 
for large aspect ratio. Additionally, our measurements demonstrate the validity of the random contact model for compacted piles of long granular cylinders.
