I am guessing you got the information that 'manzano' means 'apple' in Spanish from the New Mexico Falcon Guide where the same error is made, but it actually means 'apple tree'.
manzana = apple
manzano = apple tree
oliva = olive
olivo = olive tree
Be advised that FR253 may be closed during winter months. I planned to hike Manzano Feb. 6 2006, but found the road gated off just past Manzano State Park. The signed said it was closed in winter "for resource protection." I don't know if FS422 might be open from Abo Pass to the south, at least far enough to access Pine Shadow Trail. FS 275 from Punta de Agua is another possibility, but again I have no idea how far the closure extends over these roads. I can't find any reference to the subject on the Forest Service website. If you are similarly unlucky, the closest alternative is to take FS 245 out of Manzano and hike Osha Peak instead.
