I have driven and ridden it several times. It is quite scenic, on the north end your riding in the flat land then jump up into the mountains your kinda riding along the Rockies. I have not been on it since 2015, at that time the pavement was getting chewed up here and there. There is forestry road access off of it so you can encounter muddy sections where the heavy rigs enter the road. The only services I recall would be at Grande Cache. Gas, food and Lodging are available.
We might be riding it in early June If I do I will post up an update for you.
