On my bike at Costco last week, I was approached by a nice gal in a wheelchair - she gave me the flyer below. Evidently, somebody is working on getting a hot air balloon wheelchair accessible - and the proceeds from this fun run will get a few such folks up in the air.
I found this YouTube video giving more details, which has the gal that approached me in it as well.
Sounds like it might be a fun ride for a good cause - feel free to share and/or join in.
