Monday on TV: KUED takes us on a trip down Lagoon's memory lane

KUED-Ch. 7 takes a look at a Utah institution in "Lagoon: Rock and Rollercoasters" (7 p.m., Ch. 7).

It's a bit heavy on talking heads, but this relatively brief (about 39 minutes) documentary about the Farmington amusement park is filled with some nice photos, video, some interesting history and some great memories.

It's fun.
