I’ve always envied people who own hot tubs. There are the obvious reasons—warm water relieves aches and pains after epic days in the backcountry, and soaking with friends and family is a companionable way to pass time (even the most avid texters/selfie takers soon tire of holding their phones above water). But there’s also that iconic mental image I have of lounging in a bubbly outdoor spa, surrounded by 104 degree F water, a cold après ski beer in hand, and the sky turning scarlet and burnt orange as the sun drops below the horizon.
