Anyway, I was using Microsoft Streets and Trips 2001 to get driving directions to some geocaches when I noticed this oddity.
Streets and Trips refuses to route via the Colonial National Historic Parkway if the destination is anywhere off the parkway, even if the parkway would bring you the closest to that point. Instead, it uses some local roads and then tells you to cut across some woods or fields, a swamp, and the parkway!
I played around with it a bit to see if I could force it to route through the parkway. Placing some intermediate stops on the parkway didn't help. It plotted a route to those stops then goes back out to Route 199 and back to the local roads and the same weird approach.
Oh, by the way, if you're familiar with the location in the map then you can guess where I'll be heading for vacation next month. But in any case, all will be revealed soon enough... heheh.
Also, I just made reservations at the Mariott in Philly for PhilCon. I wasn't planning to go since one stay at the Adam's Mark per year is quite enough. But I checked the Philcon website and noticed that they're using a different hotel this year and the room rate is more affordable so I might as well check it out. Besides, if I get bored at the con, there are some new Philly-area geocaches to visit. :)
By the way, I just love the ease with which I was able to reserve the room online at the Mariott website. I could even enter the Philcon group code to get the convention rate. It's a straightforward process and unlike a reservation clerk, I won't misspell my name.
