That an Esquire Club was located at 1438 Del Paso Boulevard in North Sacramento is NOT in debate. Because the road was former U.S. 40, there is an onsite "blog" showing the businesses that are and were on that highway route:

The Wildebeest will even give a "leap of faith" for the 1940-44 time frame for its operation. BOINNNNG!

I think the "proof" Jay would like to see is whether the L-in-big-C zigzag chips (in several wonderful colors) came from that location and nowhere else. Many of the L-C chips seem to show up around the Sacramento area from time-to-time (I never see any at San Diego swap meets, for example) so their source would seem to be from that area, as opposed to say, Kenya, where our Wildebeest has now landed up to its knees in river mud. SPLAAAAAT!
