To my knowledge, that is the only city owned swimming pool in Danville. I can't be certain that there are signs on other city property. During a conversation with the city attorney, he said, "Well surely, we can agree that the city has the authority to ban guns in city buildings". I did not respond, because I didn't know if Danville had a city ordinance, I still don't know. I do know that I have looked through all of their published ordinances and I can't find one. This issue may have escalated to more than just the pool. Since you are going to be in town, I thought you might be able to take a look. If you can't, I'll still get by. Thanks for whatever you can do.
