>>1538742I mailed my microspikes to me at Idyllwild (around mile 150ish) so I could hike up Mt San Jancinto, I then sent them to Kennedy Meadows (mile 700) after I had summit San Jan. Post offices will usually hold packages for a couple weeks and there are stores along trail you can send them to and they'll hold them for a long time and you just need to pay a small 3-5$ fee to pick up your packages from them.
I didn't own a proper ice axe before this so I just bought on in Kennedy
