Put it on the scrape, that buck will vist up to 3 times a day and if you drop some buck urine on the scrape you will cause the buck to stick around, to see his competition/intruder.
The trail is made by a bunch of does and the bucks aren't as likely to be with them yet, though in indiana it appears it will be an early rut. Made a mock scrape last year, becuase the buck I seen wouldn't use a predictable trail, set my camera up on the same tree i made the mock scrape on, and got one good pic of the buck about a 1/2 hour before daylight.
Definately what he said!
