Some counties or other local governmental units may have a restriction in the form of a local ordinance that restricts hunting methods. The 10 foot regulation may be silly but it does exist in some places. There are 10 foot above ground ordinances in some areas, but this is not a statewide regulation.
Search for ordinances in the areas that you intend to hunt, ask at the local sporting goods store, or phone the local warden for clarification. Asking for law clarification on an internet forum can quite obviously result in big problems due to misinformation.
Good luck to you.
