I read an article that claimed that active dates (doing something like hiking up a mountain or rock climbing) bring people closer together and make your partner seem more attractive. In that vein, maybe you should check out a state park for Valentine's Day (I included Little Rock Rock Climbing Club in the top places to bring a date. Perhaps simulated climbing is arousing enough).
If your love is more sedate, there are other ideas, like visiting the Old Mill or going to a movie. Check out the whole list for more details.
