Ohhh...let's see...
Shreddies (still have them today..not the same box mind you )
Cap'n Crunch
Sugar Crisp (remember Sugar Bear?: "Can't get enough of that Sugar Crisp")
Sugar Frosted Flakes (...Tony the Tiger: "They're Grrrreat!")
Sugar Pops ("Are tops")
Trix ("Silly rabbit...Trix are for kids")
Corn Flakes
Rice Krispies (I can still remember the jingle)
Special K (sometimes)
Shredded Wheat
Corn Chex, Wheat Chex, Rice Chex (usually just the corn)
These days it's either Corn Flakes, Shreddies, or my current favourite, Nature's Path - Flax Plus granola (with pumpkin seed)...I think I'll have some right now, excuse me....
