I am on a cross country trek from acadia maine to san diego ca.  on my first night after a long day up bubble rock in maine I returned to my site. I notice very quickly some stranger had totally swiped my  tent's fly!!  I am using trash bags and its not the best for ventilation... I'm very bummed... I would pay if anyone who had a Rain fly for my tent! shipping and  the whole  works!  I talked to rei and got "NO WHERE!" not so awesome with customer service!  I'm looking for someone to help my journey, someone to save my trip from disaster.... Please
