A Vacation for Tyler and Mommy

Tyler is almost 7.  He's so' sweet, so intune with people's feelings, so in love with his animals, and he adores his mom Jennie more than anything in the world.
I am his auntie.  I take care of him, because his mom has terminal cancer.  She was diagnosed with terminal rectal cancer when Tyler was 3 years old.  Shes been through lots of surgeries and rounds of chemo.  Today she has 5 spots on her lungs and 5 spots on her liver.  The chemotherapy is doing its job at keeping the spots small, but the toll that this has taken on her body is alot.  The things she can do with Tyler are very limited, and the time will come when the chemo will no longer work on her cancer.
Before that time comes, before Jennie's body will not let her get out of bed at all, Id like Tyler to have a vacation with his mommy.  They have never been on a vacation together.  I'd love for him to make memories that he can carry with him forever.  She won't be with him for all the ups and downs of high school, to hold him through his first heartache, to teach him how to drive.  I think of these things every day.  I think of when the day comes that we will have to tell him that his mommy is going to Heaven.  While Tyler is still innocent, and while Jennie still has strength left in her body I want so much to give them this trip.  I want to give him this time with his mommy so he can carry it in his heart forever. 
My goal is to raise enough money for them to take a vacation in June when he is out of school for Summer.  Thank you for your help and support from the bottom of my heart.
