Jerry,
A Bluetick that has a cold nose is a lot more common that a cur tracking 16 hr old imprints. Both types of dogs have their strengths and weaknesses. However, true cold-nosed is not a cur trait. Most guys that hunt curs will tell you a 2.5 hr old track is a lot for a cur. I know there are exceptions, but not 16 hours worth of them.
You do realize that the dog Jerry is talking about is a BLUE LACY not a BLUE TICK!
No, I did not realize that. Thank you for telling me.
