I want to get a bike rack that carries two bikes, preferably one that attaches to the back. Does anyone know if the Subaru rack is easy to use? Can one get in and out of the back without taking the bikes off? I keep my dogs in the back (have a dog gate), I would like to get them out without always taking the bikes off. I haven't seen one of these racks close up, so I don't know how they work. The last bike rack I had was a generic one for my Toyota. Thanks for any input you might have.
