I get the most interesting tips from fellow playgroup mothers! Today’s post is one example: Meet the Machines on Saturday (Apr. 26) at the Budrovich Companies headquarters, 10328 Bluff Lake Drive (off Interstate 55 in south St. Louis County).

Between 10 a.m. and 3 p.m., parents and kids ages 3 to 15 can come to the north entrance of the company’s “bone yard,” in an old quarry, to register for the event. Then the kids can climb around on actual excavation, earthmoving and hoisting equipment, as well as operate cranes and motor graders on a training simulator and see helicopters, a monster truck and a top fuel dragster. It sounds very dirty, a little dangerous — and very wonderful for boys who love construction toys. (For a full list of other participants and activities, see the online press release.) The first 1,500 visitors get goodie bags and hard hats (probably not a bad idea!); food and drinks are provided for everyone for free.
