One of the things I enjoy about writing is taking research trips. These have included an Alaskan cruise (the setting the fourth book in my Paul Jacobson Geezer-lit Mystery Series, Cruising in Your Eighties Is Murder) and visits to Venice Beach, California, (location of Senior Moments Are Murder).
We just returned from a two night stay in Glenwood Springs, Colorado. I have a manuscript that takes place there, and it addition to a nice vacation at the hot springs, I wanted to check on several of the scenes I had written. Good thing. I discovered a major error. I had an important scene where my protagonist goes down to the Colorado River. The problem: the place I used didn’t work because of a small impediment: I-70 runs along the river with no way over or under the freeway at that point. By walking around, I found a pedestrian bridge that crossed the freeway and ended up in a lovely park, Two Rivers Park. With some minor editing, I can now set it right.
