Kevin,
That paint strainer filters idea is genius!
Top 5 for me in terms of improving the experience would be:
Sriracha: My preference of spicy stuff for the trail food.
Kindle: UL peace of mind and all the books I can read.
Umbrella: Incredible for the south country sun, lots of comments on mine on training trek.
Sunscreen: Paid handsomely TOTT buying last year, will be investing in “the good stuff” in advance
Crazy Creek: Hard to amend with my UL beliefs, but there are tons of times as a ranger that don’t exist in normal backpacking like teaching that a nice chair is appropriate for and thus worthwhile.
For Crews:
Standardized cookware: Worth simplifying bowls to be foldable plastic ones that are easier to slarp and even easier to pack, thus treating them more like crew gear than personal gear.
Additional gallon ziplocs: Always convenient for stuffsacks/additional yum yum bags
A deck of cards or simple game most of the crew plays: Simple to build group dynamic/take up time in camp. I like settlers of catan gutted to the essentials in aforementioned gallon ziplocs.
Seasonings: Don’t underestimate the power of S&P or even a curry on the mountain house they give you. Your preference of hot sauce.
Gaiters: A pair of dirty girls are worth their weight 100x even if you were to only put them on climbing baldy. Never underestimate the power of being the person who barely ever has to mess with their shoes while hiking! In a group of 12 it can really eat up time!
Ironically I have never seen any atrocities because I’ve never taken any Philmont crews out myself with being closed last summer. My biggest so far was another staff member:when I went there as a scout our ranger brought a full size mallet for his tent stakes. Being I was the crew leader and trying to spearhead the lightweight charge for the rest of my group, it hurt more than it should have.
I did take some NT crews out last summer, and by far the most impressive atrocity was a full frame DSLR with full body waterproofing- That I only saw on the last day of the trip! Unbelievable! these kids caught fish in camp… and the camera sat in the pack!
