That's what he said too, but the reason the problem came up is on the way home after a game at Flag Raiders, a semi aggressive bus driver questioned us regarding the contents of our gun bags. I explained to her that it is perfectly legal to transport, and nothing relevant was on the GRT website; the closest thing being no large sporting goods unless they are in a case.
The next day I called the GRT and spoke with the security manager, because I wanted to make sure we weren't doing anything illegal. He said what I already posted, and we agreed that if these are the rules, the website should state them for safety reasons.
