No Big Cameras, please

Recently I dug out some old photos I took a couple of years ago during one of my daughter's Girl Scout outings. These were from an exotic animal rescue center here in TX.

What I happened to remember was that while nearly everyone there had a camera, they singled me out because I had a DSLR. I had to sign a waiver saying I wouldn't sell the images (I had no intention to) or publish them. The wording was kind of vague on web use, but they told me if it's just on my blog it's ok. No problem with that, other than the fact that they don't realize people sell images made with point and shoots too, but whatever. I understand why they don't want someone profiting from these animals (they're all rescues and some were abused). But they make compact cameras that can shoot uncompressed RAW images that come close to what a DSLR can do. Anybody with any kind of camera is capable of producing images that can be sold.

The big cats were behind two fences, so it was impossible to get a clear shot anyway.

Then just today my wife was making arrangements to go on a nature walk through a wolf preserve while we're on vacation next month. Their rules are no cameras "with a larger than 70mm lens." My smallest lens is a 24-105 zoom, so would that be a problem? What if I promised to stay 70mm or lower? Even if my camera has a cropped sensor (like almost ALL consumer cameras) 70mm could actual mean 90mm. When my wife called to ask she was told "we just don't want any big cameras." Now I'm wondering what they consider "big." A DSLR? Probably. Same situation as before except they're worried about lens size. Guaranteed I'm going to have a problem when I get there.
