What would be a good romantic birth day gift for a sporty girl?

Sporty or not girls love expensive gifts. she won't be sarcastic with a nice watch or earrings or some good quality perfume http://valentinelovecard.com/pg_store.php

Matching sleeping bags.

Try a personal gift from the heart. have a gift basket made up for her with the things she likes. You can also make it for the both of you to do something together. Check out this site. You also can tell the lady what you like and want in the basket or she can make a perfect one with the ideas you have given her. So look at some of the baskets she has made and then email her and talk to her about what you are looking for and she will help you.

Look into hiking tours in your area... something that you can do together that is at a level you both can do, but not TOO easy. Something that will be fun, challenging and memorable.

Well, if you really want to make it memorable and nobody or nothing could top, here it goes...Find a nearest place where you can book a Sky Dive session for both of you and have her filmed on video when she makes the jump and they give you the CD to take home on the spot. Afterwards, take her to a nice restaurant, good food, some cocktails and give her a small gift to open as girls like that. She will not shut up talking about it to you and her family and friends for days and she will thank you greatly for the special gifts. Get more tips like this at www.WhatGifts.com like I did and best of luck.

Get some photos of her and make a photo book of her playing sports and get some good shots. You can throw somepictures of the two of you in there as well. I think this would be a good idea because at http://www.smilebooks.com you can customize a book and its not to pricey either. I got one for my girlfriend and she absolutley loves it to death. Check it out i think it can help!
