A Google search for Looney Tunes references to Cucamonga (how many people can consider something like this part of their job duties?) turned up a “Did You Know?” page about Rancho Cucamonga from a tree service directory, of all places. Here’s the link.

I suspect all the “facts” aren’t 100 percent accurate. The trivia note that Frank Zappa made Cucamonga “his part-time residence for much of the ’60s and ’70s” makes it sound like he had a summer home there, when in reality he lived there about a year circa ’64. So caveat emptor — but much of the other info sounds right.
