Over 225,000 people (which is destined to grow as the job market continues to expand; Tesla's Gigafactory is one of several potential sources of employment within the next half-decade), and they already hire a boatload of Reno residents for the distribution center there; hiring a handful of delivery people and picking up a few more delivery trucks would be a drop in the bucket for them.

Oh well. I'm sure it's just a matter of time before drone deliveries become the norm.
