Red Bound

At what point is it too cold to go ice fishing?   I am going to try and test that theory this weekend on Upper Red Lake.  The temps here in the cities have been well below zero for almost a week.  Now head alomost three hundred miles north and out on a frozen lake 8 miles and let me know what the temp is.  The temps on Red have ranged from 0 to -35 for the last 14 days.  This weekend should be no different.   I will report back with pictures and stories upon my return.  Fish On!
