Name these "certain rich and powerful people," please.
I'm actually in favor of such a monument, if designed properly. I envision:
A pile of Bovine excrement (refreshed daily by VD infected Berkeley co-eds offering "free-love" to passers-by after rolling in the replaced material and spraying themselves with patchoulli oil), fashioned into the shape of a peace sign, colored in the French Tricolor design, with a yellow stripe on the obverse, a sound system blasting "Hell No, We Won't Go" at 250+ decibels, and Dr. Leary handing out Libertarian Party pamphlets printed in LSD laced ink on smokable Hemp Paper.
This will represent the true essence, in every sense, of the 60's that many wish would have never ended. And for those people:
We then announce the site as the location of the "2005 Burning Man Festival, Move-on.org, and International ANSWER Harmonic Convergence Vigil" and ready the airstrike.
