Taking route 9 up to Wilmington is great. Once you get to New castle County take a drive up rt. 52 into Greenville where all of the Dupont land is. From this point your options really open up. Once you get up near and around the museum of natural history just bang a left onto any of the back roads and try to get lost. BEWARE OF BIKERS, especially on nice days. You can take any of these roads into PA. I don't know the actual names of the roads back there even though I'm from the area, sorry. Bottom line, get up to rt. 52 near the PA border, take a left and see where you end up. Also, take 52 up to route 1 in Pa and then turn left on to rt. 1 towards Longwood Gardens. Turn into the Longwood Gardens entrance, and take a left past the main entrance. There is a small road that takes you around the gardens that ultimately lead to some more fantastic driving. Dammit, I think you should be looking for rt. 58 in Pa. For the third time, get to 52 and explore. I hope my horrible explanations help. I've been beating up my E90 330i on those backroads for the past 2 years along with several beaters that I've pushed since I hit 16. Even though I give awful directions, I could happily and easily show you what I speak of......if you let me drive your Cayman. Just kidding.......sort of.
