Alzheimer's is a Horrible disease... Help me in the FIGHT!

Hello Friends,
I am very passionate about Alzheimer's Disease. My father suffers and just on Saturday we experienced the scariest thing.. It was 11am and I walked passes my parents bedroom and saw the room empty. I walked to our family room and saw my mom taking a nap sitting up on the couch. I asked, Mom where is Dad? and she said, oh he's sleeping. I informed her he wasn't in the room. (sidebar- my dad gets very confused and disoriented and doesn't like walking around) I searched every room in our house and panic set in. My dad was gone.. I ran into the living room and saw the door closed but unlocked. In my jammies, I ran outside and started yelling dad... nothing... Paul in the mean time got our keys and started driving around the neighborhood. I drove around too and my mom stood home.. We searched everywhere and stopped anyone walking to ask if they've seen my dad.. Finally after what seemed like hours, I came upon a black truck and pulled up aside him.. I started to ask about seeing my dad and the man moved back and there was my dad sitting next to him..
You don't know how happy I was...
My dad had wandered 4 blocks away in his pjs, no shoes and was found by this very kind man. The man had driven him around for approx 35 min before I found them.  My dad couldn't tell the man his name nor did he know how to find our home... If you have a family member or friend with Alzheimer's you know how incredibly scary and sad this disease is..  I see my father suffering and over the past year he has had so many additional medical conditions. I need to be his voice.. I have started a team and we accomplished out first fundraising walk last Oct.
Today, I ask you to help. Use your voice and signature... Below is a link to the foundations petition.
If you can find a few minutes to read it and sign it I'd appreciate it so so much..

From my family and I...I thank you dearly!
