Listen. I'm the kind of person that HATES buying gear before I've earned it. I raced a hand-me-down bike for 2 years before I even thought about buying a new one, and I think I rode for an entire year with regular ol' spandex before I bought a pair of chamois shorts on sale out of curiosity. So I'm cringing a little inside every time I swipe my card to buy another piece of gear for this trip.
Some of it seems like a good investment - for now. Like my Giro wool cycling jersey. Some of it already seems overkill - like the Garmin eTrex20 that retails for close to $200 and then costs an additional $200 to load with the proper topo maps for the GDMBR. And if you skip the topo maps and just stick with the basemap, you might - like I did - accidentally delete the basemap because the file is not protected in any way and very easy to delete, and when you call to get it figured out they say that they either have to take control of your computer to send you the file or you have to MAIL. IT. BACK. IN. .... i'm getting sidetracked.
Anyway, the point is that about half of my stuff is very specific to the trip I'm doing. E.g., the ultra-cool Columbia SPF 40 longsleeve shirt. (And now we can all ponder what that actually means and if our winter sweaters are SPF 100.)
The only way to make myself feel better about all of this is to line it all up in a semi-organized fashion and take fun timelapse pictures. I must say, the Blackburn Design bags do a pretty good job of gobbling up all the gear and stowing it securely away. Very satisfying.
