If they just mixed Purell into the road sweepers maybe they could cover more ground

Back in November a loose coalition of coreligionists announced a purity siege upon federal interstate highway 35. For those who misses the events, or have forgotten the details, here's a summary from Austin,Texas:

Christians said the Old Testament's book of Isaiah prophesizes I-35 will be the United States' "Highway of Holiness."

Isaiah 35:8 reads: "And a highway will be there; it will be called the Way of Holiness. The unclean will not journey on it; it will be for those who walk in that Way; wicked fools will not go about on it."

"Everything we do, we want to make sure scripture is backing us up," said Austin's PromiseLand Church Pastor Charlie Lujan. "I-35 being Isaiah 35, it just matched."

In February NPR reported the effort was being renewed, at least in the Dallas area.

(Nor is the campaign limited to the one interstate. A website, Light the Highway, says "participants do not believe that Isaiah actually refers to Interstate 35. Rather, it says, the Bible is used symbolically "as a catalyst to begin praying, just like those who live in Interstate 40 can use Isaiah 40:3," NPR continued. The last time the website was updated was October 30, 2007, and it has been visited by 897 people as of today.)

Lujan conducted a five-week 24-hour prayer vigil and organized what he called a "purity siege" along Austin's famed Sixth Street.

The sieges are part of the I-35 project, a nationwide movement to save those at bars, gay clubs and abortion clinics in cities along the interstate.

"If you just draw a line right down the middle of the nation, and go to these strategic cities along the way and just cry out holiness and purity, we believe there's going to be a referendum, a change, a radical change in our nation," Lujan said."

So far there don't seem to be any quantifiable results of the purity sieges, other than a 19 year old kid in Texas who got swooped down on outside a gay bar, then shipped off to an ex-gay camp, dunned for $2100 plus $150 a week board, and chucked out for refusing to stop being gay.
