i had planned on spending two nights in Yosemite, but something came up and i only spent one... so i went to the camp reservation building, walked in and saw two employees talking to a woman who was looking for a campsite, she was sooooooooooooo disappointed that she and her family had driven alll the way there, to find not a single campsite anywhere.... i said "excuse me, but i have a free campsite if anyone needs it"... the lady (she was from Germany) looked stunned at me and then looked at the employees... the employee said "are you serious? cuz if you are, this lady would love it!!!"... i told her it was hers... she was soooooo happy... she offered to pay me for it, but i told her and her two little girls (and her husband) to enjoy their time in Yosemite.
