[AT] OT - Types of gravel

[Mike]

Hi All, we have a horse paddock that is about 75' x 75'. It is currently 
filled with a mixture of manure and clay about a foot deep. I'm going to 
scrape it clean, and want to replace it with some sort of gravel. The 
choices seem endless depending who I talk to. What I'm looking for is a 
type of mixture that has smooth rather than crushed stone, with a lot of 
fines to help lock it together. Now the exact product I'm looking for 
many not exist, but any help getting me close would be greatly 
appreciated. Just a further note, our paddock has a slight grade to it, 
maybe 2-1/2 to 3 Ft in 75 ft.

Thanks for any help,
Mike M
