Surfboard blank... or roof bars?

Seen a very cheap longboard blank already shaped that id like to snap up. Thing is its a ten footer and wont fit inside my little van. Is trying to put it on the roof bars mad? Could have another longboard underneath to avoid dents. Or even sandwhich it between two boards…

Wouldnt be going over 50mph but its a 2 hour drive… what do y’all think should i risk it?

I say go for it - sandwich it between two longboards - why not?

go for it. sounds like at the minimum a good story.
