Matt, great post and photos. Please post more!
You said you expected some input so here's mine:
I've been looking forward to testing my metal on the boving route for a while. I usually put the boving route on my late july/august list for the year and each year I get pre-occupied trying to finish projects that I started earlier in the summer, this year was no different.
As is, your route is a bold direct passage up an otherwise blank slab. A testament to your vision and skills 33 years ago! While I can understand the disappointment in having so many years pass with few repeats and very little praise, retro-bolting the rig seems a bit drastic.
There are lots of well protected moderate routes in the vicinity to climb on that can be easily done in a day (which im sure you know!): D Tail: Serpentine, Backbone, Gerber-Sink, NE Buttress. Leche le Vaca and the NEB on CBR. Acid Baby on the Spineless Prow. NEB of Colchuck
And now there are some hard technical free-climbs in the area: The Tempest, Dragons of Eden, Let it Burn....
I see the Boving Route fitting right in the middle. Accessible to the 5.10 climber who wants a challenge and adventure, who's done the other moderates and wants something harder, but isn't up for 11+/12 free-climbing of the testpieces.
With that being said, it's your route and obviously you can rightfully make any changes that you see fit. I've always felt that before you can have an opinion about someones route you should climb it first, so, in reality, this blabbering on by me is a bunch of bs. I definitely value Joe and Mark's opinion, and you guys seem to have a similar vision, perhaps the route would be better with bolts. Nonetheless, I can't help but think it would be a damn shame that the old skool challenge and boldness of your line would be forever lost...
I am against bolted rap anchors on dtail. People keep saying that want to turn D-tail into a crag but to me it will always be a Mountain.
