Is the norm around here to still use 2m, and a short yagi for the DF?
Depends on the hunt.
Mobile hunts are often on 2m because so many hams have 2m radios
that they can use, and it isn't too difficult to stick a quad or yagi on a
mast out the window.
The international style sport of ARDF ("Amateur Radio Direction Finding")
does have supporters, and the US (technically the ARRL) has fielded a
team for World Championship events since 1998. That has competitions
on both 2m and 80m, and is a map-and-compass exercise on foot in a
forest. But the pool of participants is relatively small compared to the
overall ham population in the US, and receivers designed for that purpose,
especially on 80m, are not very common.
