I've been out there with a buddy drilling a dry tool traverse in, finished yesterday and it is very fun, if anyone wants to get the picks out
the rock traverse on the main wall is nails but sill goes
I have hardware for anyone who wants to put something new in,
the other traverse needs a lot of work too but probably better to focus on the main one for now.
i have also scrapped, and prepped a few spots for new holds along the main traverse in the middle and i have some glue that will hopefully work
as far as prepping the concrete i have been using the sharp end of my hammer to break away the surface and then pounding it flat before scraping with a wire then regular brush.
bolt on holds are fun but become brittle quickly out there for some reason, and expensive unless anyones got a box of old ones laying around
