Most of my time is here at rokslide, great place and learn a lot. I like sites where learning and sharing versus heated debates.
Forums I used to love, but frequent less is knife forums (kinda died with new owners)/ blade forums cause I'm a knife nut. Also whaler/continue wave as I love my whaler too.
I mainly follow this site and monstermuleys. There is a lot of good information on MM, but the owner (Founder) getting involved in controversial debates is sometimes too much. Man I wish that guy would just stay off the site and just collect his profits.....
Rokslide is awesome though. I like how it's not just information on specific hunting spots, but also information on survival, camping, products, and many more topics.
I used to go on AT a lot, about 10-12 years ago but there were too many anti-hunters and anti-gun folks on there. Back then, anyway. Might have to try it again.
