People do need to realize that this is a hobby and not a science. There is more than one right way to go about do things.

For instance, I've kept several leopard geckos on sand for years and have never had any problems (of course I feed outsde the cage). Likewise, I personally hate repti-carpet with a passion. However, its not fair for me to tell everyone that they must use sand always and never use carpet. What works for me may nto work for everyone. Many people out there need to remember that when it comes to giving advice.
