this is some great stuff and will try and use it on my next trip. my only cycling experience in japan so far went like so>trying to do onomichi to imabari in a day to go over all the bridges and see the towel museum>after the second bridge weather takes a turn and starts pouring>on the downhill after the third bridge i fly over my handlebars and take a chunk out of my left hand>bleeding profusely i make it down to the 7/11 at the base of the bridge and ask the girl working for the “ichiban big bandaid-o”>scare a guy trying to come into the bathroom as each time i try and clean out my wound i yelp from the pain>still manage to enjoy kousanji temple before needing to get on the ferry back to onomichipicrel is some shitty みかん drink with blood coming through my patch job
