Warwarsing Boulder Climbing

Greene and Russo, mention only three problems on the back of the Warwarsing boulder, when there are at least 5 obvious lines. U-Turn is easily identifiable, but the exact locations of Guardrail and Hairpin Turn are significantly less so. The included drawing and descriptions provide little illumination. Hairpin Turn's description reads, "Start on low horizontal. Climb face." Really? Thanks. Guardrail includes the instruction, "Sit start on low edges, climb small face. Climb straight up the corner." There's nothing on that side of the boulder that I would really call a corner. There is a vertical crack, but no real face below it. I've attempted to correctly identify these climbs and have inserted two additional lines. I've also regraded them, since several of the problems are significantly harder than Oncoming Traffic (originally V1 in the book, now downgraded to V0) on the front side of the boulder. If you have information or input as to whether or not I've correctly marked the climbs, please get in touch with me and I will make corrections. Also, please submit grade suggestions for all these problems and I will amend the published information accordingly.
