Congrats! I also found some very fresh (same morning due to snow evidence) gulo tracks last Saturday and set it up, but will not get back to check until this weekend.
Do you, or others, notice recent "return visits" like this often?...doubling back, etc... or did you move "ahead" of the sign and get him where he WENT instead of where you found the sign?... I am sure it all depends on a lot of factors - attractiveness of an area, wind, serendipity, whatever...but just curious.
I always feel like when I come across super fresh sign, I set it with a stinky lure hoping they will 'double back', but I have never had this be the case. Usually they make me wait a looooooong time before any returns...
