[Out the gate, onto the bike, and onto the road - he's singularly-minded right now, just trying to get them out of the way of the imminent explosion. They don't have to go far, and don't have time to, anyway - just up the road a few seconds so that the main building, with its exhibits and gift shop, is between them and that truck. There's just enough of a rise on the road here in these low hills where he can wheel around and face the blast right as it occurs.

A cloud made of fire ripples outward in all directions, sending the shockwave through the ground and the air itself, though the effect is dampened greatly by the time it reaches them. The truck is gone by the time the brilliance of that explosion dims, the portable office mostly rubble, and the fence flattened in a ring around it.

As the dust settles and ash from burned paper rains down, Johnnie takes the bike back to the parking lot between the burning buildings.]

Just one more thing I wanna do here before we go into town. Help me get those plastic strips outta the fence, or anything else long. Pieces of wood.

[He parks and hops off, ties his bandana around his face to keep dust and ash out, then heads right toward the downed fence and starts to rip slats out of the chain link weave.]
