Wow, looks great despite all your tribulation! I'm from southwest Louisiana, I had a wonderful 'dump truck cake' that I posted on the 3D area that was precious when left my house and melted when I got to the customers house. They loved it anyway and said it looked like I made it that way on purpose, but I could have cried. I notice someone said they use meringue powder to stabilize buttercream due to the heat, I think from now on I'll try this and I'll also remember to turn on my 'rear' air conditioner, as well as buying ice packs! Your cake was great!
