I'm planning a trip from west central Georgia to Bay City, MI, to Wichita, KS, to Irving, TX and back to Georgia. I have S&T 2008 and SA 2009. Part of the fun in taking a trip is the planning so I put the information into both programs.
S&T did a spectacular job. The only change was to avoid I-75 through Dayton. I moved the route to I-675.
DeLorme tried to take me on the ride of my life. An example would be in Michigan. Going north, it routed me through Lansing (40 miles west) and through Flint rather than beside it. Anyone who's made the trip know U.S. 23, a limited access road, is almost a straight shot from Toledo to Bay City.
Going south, it routed me on I-75 through Detroit then west to Battle Creek on the way toward Lake Michigan. I'd rather be set on fire for 15 minutes than to drive through Detroit. In addition, I-75 is almost completely shut down for construction in and around Detroit.
From Chicago, it routed me north to Wisconsin and Minnesota then south rather than due west to Des Moines
I had to put in 5 "route avoid" areas to keep DeLorme from adding an extra 350+ miles to the trip. I've made the trip to Bay City many times and could almost drive it blindfolded. Adding Wichita and Irving to the mix caused the program to have a coronary.
Many years ago, I was a big supporter of DeLorme. This was when they first put out consumer mapping programs. In the last few years, I've become disenchanted with them and am changing my allegiance to S&T. For a Microsoft program, it's pretty good.
Has anyone else had these anomalies with DeLorme?
One thing about the road choices made by SA: Generally, both the shortest (and the quickest) routes were interstates. SA elected to choose OTHER interstate routes that were way out of the way. As I said, leaving the Chicago area, SA took me north to Wisconsin, west to Minnesota then south to Des Moines. The route due west from Chicago by interstate was direct to Des Moines.
What I'm saying is, preferences notwithstanding, SA still chose interstates but they weren't even close to being either the quickest or the shortest.
