I just read a post about hand sanitizer and GI upsets off the river, and realized this could be a great topic for discussion. The "search" was fruitless, so how many squirts of hand sanitizer should one use? Do you use more after peeing, pooping, is there a point when too much is not better? Should you use a different strength on multi day trips vs day trips vs BBQ's. What kind do you like? Is there any advantage to different scents?
