How can you talk about San Dimas and not mention the only reason for its continued existence?
If it wasn't for the fact that all the Southern Californians use Raging Waters to prevent spontaneous combustion during the 450-degree summers, San Dimas would have been totally consumed by tract housing and corner malls long ago.
That freakish waterslide that is basically a 60'-freefall is reason enough. I'm sure it was designed by some madman for the express purpose of removing swim wear.
Raging Waters was disguised as Waterloo in Bill and Ted's Excellent Adventure.
