Rita's Coffeehouse and Eatery has sadly made the announcement that they will be closed indefinitely. It was kind of a sudden announcement and they did say anyone who has ordered frozen meals will receive them. I am so sad to hear of this closure.
Just in case you didn't know, it is illegal to try to bring a firearm on an airplane without properly storing it and checking a bag. So, no you cannot bring a gun on an airplane with a carry-on bag. You can bring a gun on an airplane though.
