Nothing like a dip in a lake or a river on a hot day plus it makes it harder for mosquitos to find me and less body area exposed.
I've been skinny dipping for 50 yrs , mostly in wilderness areas, and never had a problem as far as other people since the few people I rarely encounter are often fellow skinny dippers. Not appropriate at the public swimming pool but acceptable in the wild.
Good advice about inflating a mattress. The first air mattress I got sprung a leak and I spent the mornings waking up on hard ground. Just bought a new one and will give it more TLC.
I used to have a Thermarest self inflating and it lasted 10 yrs.
Decided to go air mattress for comfort and weight savings but may go back to self inflating if I continue to have leak problems.
