We just purchased a 2007 Forester yesterday. It is our first Subaru and I am really looking forward to driving it! We have previously driven vans, so could just throw our skis inside as there was plenty of room. Now I need to come up with a roof top system, but don't want to spend tons of money. Our Forester does not have the cross bars, so will I need to get some? Or is there a Thule that will just fit onto the side bars? Forgive my ignorance and thanks for any advice!
