Hello, my tent is quite old - I'm thinking 8-10 years or so.  I can't even remember when I traded in my Half Dome for the Quarter Dome, then a new addition.  I'm hoping after I read REI's advice in more detail, I can remedy my issue.  I can't justify tossing it for a new tent with the issues I'm having.  The mesh is in fine condition, no tears, etc., so, will try to "fix it" somehow.  Thank you, and Happy New Year!
