I found a good half a dozen climbable boulders 15 minutes outside Fredericton. The rock is sedimentary and a little rotten, but nothing a lot of brushing cannot fix (I hope). Drive towards Miramichi on highway 8. Go pass Durham bridge and Dunbar brook. The road takes a long left and joins the Nashwaak river. The shoulder becomes pretty wide... park there. The boulders are right across the road, just a couple meters inside the woods. They can be seen from the road if you drive slow. I'm really hoping the rock can be cleaned enough for safe climbing, I'll give it a try in the next couple days. All the fun features are there, flakes, cracks, roofs, aretes.
Hope to see you there
