It's a shame that, with all the maintenance going on in Squamish, no one has put any effort into Grin and Holler. It was a super fun steep janky tech line just a few years ago, and I suspect it wouldn't take more than 10-15 build sessions to get running again. Maybe there's more to it than lack of initiative, but it still sucks to see a fun line fall into disrepair.
It would be sweet to get it running nice again but I think it needs a lot of drainage work so it doesn't just regress into the state it was before. I think the new climbing trail is supposed to switchback over top of it something ridiculous like 7 times so hopefully there can be a reroute and some work done to it after that goes through.
