I've been looking for a bike rack that will hold 2 adult and 1 child bikes, the problem is it looks like they're all either (a) made for a car with a trunk (b) require a hitch. We have neither, my wife drives an 06 Honda Odyssey minivan and I drive an 08 Acura RDX (Crossover Utility Vehicle) neither of which have a "trunk" nor hitch. Anyone have a recommendation that won't break the bank? Funds are tight right now. Thanks in advance!
