I just got off the phone with the Frogger at RM 615.
He's had a rough few hours in the silt beds. Trucks going by causing him to hug the high silt bed walls or scramble out. Also his the starter fuse blew and he's been too tired to kick start it so he's using a pair of pliers to jump the bike to life. He's sounds good though and is in good spirits. They are working on the bike a bit. He's not at all injured, just sore. He needed a little sit down break anyway :)
He'll be motoring on soon.
