Here are some places, in order of my personal preferance:
1# Mt. Home Rd (goes between lower Blewett Pass and Leavenworth)
2# Old Blewet Highway/Scotty Creek (starts at the top of Blewett Pass, dumps out lower on the pass)
3# Mission Creek (starts in Cashmere, just past the elementary school)
4# Camas Meadows (make sure you get past the private property)
5# Ruby Creek (dumps out on Blewett pass in the tight "S" curve deep canyon just before you break out in the lower area by Mt. Home Rd)
6# Number 2 canyon out of Wenatchee...drive to the end where there is a gate and start hiking
If you buddy can't find a nice buck in those places...I can't help much then...
