Crimsicle, I, too had thought about buying a toy bus for just that purpose, though I admit I had imagined that it might look a little weird...you know, a 54 year old woman, hovering over the dining room table, dismantling a toy bus. Oh well. I'll just wait until my husband is out of town, and I won't open my door to any visitors that day.
As to your "supporting advice," many thanks. I've read a few things today that offered similar instructions. Fortunately, a real Greyhound bus sits very close to the ground so a bus cake's supportive foam block should more easily be secreted beneath.
Skinnycakelady (The mystery of the day is this: How can oe be skinny and a cake lady at the same time?), I can't find the picture of your mobile home cake. I'd love to see it though.
If anyone one is interested, I'm planning on making a Greyhound bus cake with a person riding on top of it...wind blowing the hair back and all that. I'm titling it, "Riding the Dirty Dog," which is what we in our family call a trip on a Greyhound bus.
Lately, I seem to be into this idea of making adages and cliches into cakes; "A play on words" becomes a cake shaped and designed to look like Shakespearean play set on top of a bunch of cutout fondant words. Etc. etc. It humors me for some reason.
It must be one of those 54-year-old woman things.
