Mckenna is a spunky 3.5 year old with type 1 SMA, the most severe SMA. SMA is the #1 genetic killer of children under the age of 2. Mckenna would love the opportunity to go on a bike ride with her family. Please help Mckenna and vote for her at https://www.friendshipcircle.org/bikes/2015/02/mckenna-j/#.VObKuGPjsEK.facebook
