People and squirrels are very different. Most people will not argue that. But I find that there is one situation in which they're very similar. And that is: when I am driving towards them in my car. Then they're kind of hard to tell apart - especially if the human is kind of hairy.
Some people record onto tape, and then they pay for the tape, and download those onto a hard drive. Initially in a Pro Tools program. Other people go straight into digital, and use no tape at all.
