I think my wife has come up with a amazing idea (to me...haven't looked it up yet..but sure it has been done). We are putting the ramp together, and she remembered i have some extra roof shingles in the garage....and thought maybe we could use those for traction on the ramp! The ramp is not at a steep angle at all, so really we think they would be perfect. Want to hear from some of you seasoned vets...you think that would be alright? Thanks in advance!!!
