So I just got a shiny new Thule roof rack for my sexy honda odyssey. The 2 bike hitch rack wasn't enough, so I figured, with the U.S. open 2 weeks away why not spend a **** ton of money so I can carry 4-6 bikes and a cargo pod there? Anyways, my question is how safe is it to leave bikes on the roof rack. I might leave them on there if there's no room in the team trailer. I have the rails locked to the roof, the trays locked to the rails, and the bikes locked to the tray. Are they more a deterrent than real safety? Any thoughts? Am I asking for the bikes (or the rack) to be stolen someday?
