Welcome ms.!

Yes, you will like it. There's a huge difference between an old city bike and a decent vintage road bike. Older steel bikes often have a much better ride than modern bikes, plus they're much better looking The only real difference is the way the bike shifts gears, but for most people adapting isn't too much of a problem. Weight-wise only the top end bikes gained much of an advantage over vintage bikes. Cheap modern stuff will way more, break more and cost more than good quality vintage stuff.

They say a good road bike, vintage or not, disappears underneath you when riding along. I found this to be the case with my own vintage road bike (which is lighter than my modern one!).

Have fun looking around here, and maybe you'll meet some locals that can point you to knowledgeable shops or co-ops.
