That's where I have a problem. Reasonably flat, yes, larger than #2, definitely.
I could spread fine gravel in a "loading spot", but it'd get probably get plowed away during the winter.
On a positive note, I ordered a pair of smaller Race Ramps last year, but they sent the wrong kind so I've never used them.
Forgot all about those. Now I need to find them, and use them as Guinea Pigs.
