WAY OT: Need advice/resource on pouringconcretefordrivewayaddition

[marc at getty.net (Marc Getty)]

We would *ALL* have to sell our cars to afford enough concrete for
Josh!

He did not come to the H20 show in OC MD this year because he and his
wing screw up the tides world wide when he gets that close to the
ocean..... El Nino is just a sarcastic Spanish phrase talking about
Josh pissing in the pool you know!
