So I lined a box with aluminum foil, put the cake in it and had my mom go with me.
I drove while she held onto the cake. I'm pleased to say it was a succes. Despite my worrying of an accident occuring or the cake tipping over while in route or me dropping it or the jewels and flowers falling off.
NOTHING like that happened. It ended up being a very uneventful trip.
The cake looked perfect under Tai Pan's lighting.
I hope the bride is pleased. I am!
