or a dealer close by u that has used bikes, some do. some members at harleychatgroup has a bike or 2 for sale, not nessisarily a e-glide tho. there are members on hcg that's in the portland area, and might know somebody.
on another note: seeing how ricers like to thumb down hd posts, i suggest hd'er's return the favor...and there's alot of rice posts to mark down. respect goes both ways.
