Yeah I'd love to see the trail go further. I think the Peace River would be a nice, natural geographical end point, or maybe a bit sooner at Highway 97 / Pine LeMoray Park.
The GDTA is doing a fantastic amount of work on the trail, so it is being improved at a rapid rate. I encourage people to volunteer on some of the trail building trips this summer that will replace road walking with new trail: http://www.greatdividetrail.com/get-involved/volunteer/
Maybe in another few years once the GDTA has dealt with the major trouble spots on the current route, they can consider extending it.
That would be a good idea.
I think the route planning through that section though is critical as there are a lot of coal mines and oil/gas exploration happening in that area.
Resupply points are few and far between.
I like the idea because I live in the Dawson Creek/Tumbler Ridge area and I just feel like there's a lot of potential to develop it into something great.
When you feel life out of focus, always return to basic of life. Breathing.
