Adventure stroller for Jace

Jace is a 13 year old neonatal stroke survivor. He has left hemiplegia, cerebral palsy, and epilepsy. He is non verbal and non ambulatory. Besides watching Yo Gabba Gabba and eating snacks, Jace's favorite thing in the world is being in the water. Every summer we try to hit up the splash pads and pools. His two little sisters love to push him through the splash pad. This summer we are planning a camping trip to the Illinois river. We would love to be able to get a stroller for Jace that would allow us to easily get him over varried terrain and down to the water. On our family adventures accessiblity is our biggest hurdle. This stroller would support our ability to travel with Jace across gravel and sand, that his wheelchair is unable to  cross. We would love to take Jace to the beach in the future as well. This stroller is one resource that will help us make these dreams possible.
