>>2682872Another picture of the excursion, also gonna answer some questions from above.
>>2680244I prioritize light above all else. I try to have 3 light sources per person. Most of the mines I've explored aren't nearly as complex or cavernous as some of OP's pictures, so I don't expect to be in them for more than an hour. Other than that, just regular hiking stuff to find them, and gloves and a waterproof coat because lots of mines in my area are gross and wet.
>>2682850Rule of cool. I always hike with a gun anyways.
