I want to inspect a ways behind it; maybe a quarter mile, or so. Is it leaving footprints? Any other clues?
Search = 1d20+17, take 20 = 37
(If forced to roll because I can't spend the time, otherwise, just take 20):
Rolled 1d20+17 : 7 + 17, total 24
Knowledge (TMWNMTK) = 1d20+11
Rolled 1d20+11 : 6 + 11, total 17
