Wow- IFjane- you're mom is AMAZING!!! I'm so excited that she still wants to bike. And to think that most days in the winter, I dread the thought of riding- and I'm 50 years younger than her (I'm hanging my head in shame ). I hope to be just like your mom in another half century. Wow- I'll bet she's one fiesty woman!!!!
Go get her that trike! Heck, it looks like so much fun I'll get one and go riding with her.
