I don't know if this is "realistic" or not, but I have three units. Since the "LB" in LB Shows is my wife's initials, I decided when I needed to break my show down to name each one after my three kids (may as well get the whole fam involved), the largest being named after my oldest, and so on.
The Jack Unit: the largest with about 48-50 rides. That's my "larger fair" unit.
The Michael Unit: the county fair sized unit with about 26 rides.
The Katie Unit: Small still date unit with about 12 rides.
Of course, they get combined sometimes if I do a model show. I've been trying to eliminate as many duplicates lately as I can, hence the recent ebay offerings. Instead, I am going for same ride, different theme. For example, one unit may have a Casino and the other have a Trabant. One unit may have a Gravitron, the other a Starship.
Now onto the reminiscing...
I know this is veering off topic, but you all have got me thinking about my childhood memories at my parents' house.
As far back as I can remember, I guess I built carnival "models". Back then I had a show that I "traveled" all over the house with. I can still remember a lot of what it consisted of:
-Super Loops: Tyco slot car race track, just the loop, with a Fisher Price car.
-A Force 10: made from Construtx toys.
-A Fisher Price Merry Go Round.
-Ferris Wheel and Rocket Ride from some Disney train set we had.
-Bumper Cars: A small flipped-upside-down storage box with several one seat Fisher Price cars inside
-Spider: A Fisher Price Playground Merry Go Round propped up on something.
I seem to remember at one time or another also having a spinning top that was rigged into a Gravitron, a Tilt a Whirl made from a Fisher Price record and half Easter egg shells, a Sea Dragon built from cardboard (seriously).
Ah, the good ole days. Wish I had some photos of that.
