I took off on I-90 and about freaked at being on an Interstate again, especially one with a 75 mph speed limit. I'd been on roads with 55 mph speed limits for days that wound gently through the country side. But I was soon used to the rat race again and sat back and watched the advertising signs that sprouted from the roadsides like weeds. They were great. It's a rather bleak landscape, but I was thoroughly entertained at the myriad of signs and advertising campaigns that flooded the roadside. Wall Drug's, of course, were the most prominent. Louisiana could really take a not from this. They banned advertising along I-49 in an effort to create a scenic drive. Ummm, I-49 runs through one giant pine tree forest for 200 miles and avoids towns like the plague. In other words, it's boring. I avoid driving I-49 whenever possible on long trips, and I'm not the only one. I'd love to see miles and miles of advertising for alligator farms in Natchitoches and the boats in Shreveport rather than -- tree, tree, tree....
