How far in advance should I mail packages? Hello folks! I will be thru hiking the CDT NOBO this year and I have most of my logistics figured out, just want to get a few last details set. I plan to resupply from the trail and when it comes time for me to mail myself packages I’m wondering how far in advance I need to do so. 

Ex- it looks like Doc Campbell’s is the first place that I’ll need to send myself a box. Should I mail it from Lordsburg or Silver City? And do I need to worry about priority shipping at all? Thanks in advance!
