#1, don't bother spring Bear hunting unless you have a known hot spot or 5. Snow drifts usually mess up your travel plans to locations.
#2, chase the snow, in canyons with water. The bears will be eating fresh grass as it greens up when the snow recedes, & an occasional fawn or two if its handy.
Blind calling RARELY works. But if you see a bear, & can watch his reactions to your calling, it can be effective.
#3, bring a can of propane, & a burner & some bacon wrapped in tin foil.
Cook your lunch in a place where the prominent wind will drift into multiple canyons.
Be sure to clean up ALL of your lunch fixings. If ANY is left discarded it is considered baiting, & deemed illegal.
#4, refer back to #1. Don't bother with spring bear. Fall Bear has proven WAY more priductive where I go. Plus the meat tastes better, & Bears are typically fatter, & haven't rubbed their coats off.
All that being said, I actually put in for & drew a spring bear tag for the first time in 11 years. Now that I drew one, I gotta figure out if I even wanna go. I'll probably just take my 7 yr old turkey hunting, & if I see a bear I'll smoke it. But I just don't see actually wasting time, $, & gas trying to find one when I can just go pick out a nice fat one in the fall. Spring bear just doesn't lend itself to filling tags where I hunt.
