- On a nearby wall, holds are glued onto concrete. The wall is overhanging
- at about 30-35 degrees (very steep). The glue itself is very strong, but
- the surface of the concrete does pull away from time to time. As a result
- all of the holds are now bolted as well. The bolts aren't super tight,
- but at least they avoid a nasty fall when the glue/concrete breaks.
