Another question about photos

While I was at home over December a friend brought up a new issue. Am I going to have to get permission to use the pictures of businesses? Seems fairly likely to me. I'm guessing that most of the local businesses will allow me to use their photos, its sort of like free publicity for them and fits into the "Keep Austin Weird" theme which they all subscribe to. Another friend came up with a more Austin replacement for Q (no longer Dairy Queen) which would have previously been one of the more difficult permissions to get I suspect. I need to remember to send well worded letters, perhaps with a copy of the photo I plan on using, to each of the businesses before I reach a publishing stage.
