Hot take: My Costa Rica hike showed why a travel repair kit is non-negotiable

Last year, I was deep in a Costa Rican rainforest when my old film camera's aperture blades stuck from the damp air. I always carry a small set of jeweler's screwdrivers and a tiny bottle of isopropyl alcohol in my backpack. That day, I was able to clean the mechanism right there on a log and save the whole trip's photos. Some repairers tell me this is overkill and that vacations should be about relaxing, not working on gear. They say you risk losing parts or making things worse without a proper bench. But I've fixed three cameras on trips now and never had a failure I caused. For me, the peace of mind is worth the extra few ounces in my bag. Where do you stand on taking tools with you when you travel?
