Hey Fit, I read all of this after I responded to the PM:-)

I ride A1A from Ft.Lauderdale up into boca and north, depending on what ride my schedule calls for, unfortunatly it is one of the safer routes:-( I don't know Boynton Beach very well, so I unfortunatly am not sure of what other roads are around there. The other thing is, the safest time to ride down here is between 5:30am and 7:45am. After that the crazies come out. I do ride in the afternoons a lot(going to do it today) but you have to be super super defensive with the drivers out there on the road. The good thing though, is if you go north from where you are a1a isn't to bad! The worst part for me is getting from Ft.Lauderdale to Hillsboro bridge, once I get through there it is a lot less hectic.

I am glad you liked the Dolce, I would still go to Bike Generation and talk with them:-) They are awesome.
We sell the Jamis Aurora at Downtown, and have a few in right now on sale, but...... For what you are wanting to do I would go with the Dolce. The Aurora is a great entry level bike for someone looking for a fitness bike or road bike commuter, but if you want to continue with it and really think you will progress I would start with either a Dolce, A giant Women's frame(entry level OCR) or look into the Felt line of women's bikes. They are all in the same price range and about what you are looking for.
