In reply to bpmclimb:
When I went in about 2005, the right most death trap E3s and E2s on red slab were retro-bolted. They were enjoyable long slab routes. I mentioned the bolts to some eminent Bristol locals and they told me to go to take them out, but I never went back until very recently. Can't think why . It's almost as if a lifetime of climbing finally became available outside the winter months at Cheddar.
A few years ago (2016) I went back because my mate wanted to do some slabs, and I lived in a purportedly spiritual hive of scum and villainy down on the levels.
The hangers had been removed, so I just looped the wires of rock 3s and rock 2s over the stubs - kept things spicey.
It's a shame if they bolted on holds, but if the outdoor centre the land owner that what can we do anymore than complain about what anyone does in their back garden? Climbing ethics aren't protected by planning permission.
At the end of the day, nothing of value was lost. Whatever they do with those routes, the best thing about red slab is always going to be The Crown Inn in Churchill.
