A Collinwood playset? Wouldn't that be great? Obviously, it won't now ever happen, but when handed a lemon, make lemonade. When I was a kid, I built my own Collinwood playset out of Legos. Sometimes I built the exterior; other times I would take one of my mom's big, pull-out breadboards for a base and did interiors and then would use the small pieces of Lincoln Logs to make the characters (faces drawn on and kleenex serving as clothing) and enjoy moving them around in my re-creations of the storylines (or make up my own). I'd do my own versions of the Old House (both exterior and, on the breadboards, the interior) and even the family crypt and other sundry locations. I used a small ringbox for Barnabas' coffin (who was one of those small Lincoln Log pieces). I'd also do the same for sets and characters from Lost In Space.
