I did this ride last year and will participate again this year, probably without my DH (he has to work). It is a good MS150 warm up for the winds you encounter after Bastrop.

The ride benefits Austin ISD's Rosedale School for children with disabilities. The reason I first rode it is my Aunt works with their students. The teachers and students come out to cheer the riders and thank you for riding. It really is a good feeling.

They have a website that explains what the ride helps fund, it really gives you warm fuzzies. http://rosedaleride.org/
