We hunt next door to you in WMU 25. If it's anything like that in 18B, you can expect a lot of swamps, water, muskeg, bog etc. Argo's are probably the ultimate machines for transportation. We've been hunting 25 for 2 years and pulled young adult males both years. Terrible terrain, flat, boring, nearly impossible to walk, and estetically drab (poplars and pine trees).
The bright side.... There's moose there!!
Good luck!
PS : It was very rainy there this year, not sure about the spring. But similar to last year, so moose will be fine, but grouse populations suffer noticeably.
