While writing, a sportsman’s blind is a great opportunity for me to watch the bird feeder, and sometimes get surprised by the animals. A covey of quail scattered once when I stepped out of the blind, and I was so disappointed I’d not stayed put for only five more minutes. But for all I know, they could have been sitting behind me from the time I sat down.
It’s not unusual for me to perch my keyboard outside. I find it inspirational. It’s hard to have writer’s block if you keep moving away from it.
There's really no rule about where to write...but a word of warning... Writing in an airport is fine, but if you're a person who unconsciously lives the scenes...be aware...your face may give you away... You could be entertaining the other people around you.
