…you replace the battery for your digital scale more often than for your backpacking headlamp.
…you see trimmings from freeze dried food packages litter the floor during packing for a trip.
…you only buy lithium batteries for your (regulated) headlamp.
…you agonize between Ti tent stakes and slightly heavier but stronger and better holding MSR Groundhog stakes.
…you make a new Dana-type Wet Rib front pouch from silnylon to save 1.8 oz.
…your "significant other" says, "What are all these clothing labels doing on the floor?".
…when you KNOW it's just a matter of time before someone invents good powdered beer.
