Big doin's this weekend at Lava Lanes. 20 horses will be vying for one of the jewels of the Triple Crown; the Kentucky Derby. Here in Bend, Lava Lanes has an "off-track" betting window. Lava Lanes spokesman Peanee Denmark says come early: “Saturday will be standing room only. A lot of people come in from all over to make bets and watch the race. Actually we open at 8 o’clock for betting because there’s lots of races because there’s lof races that go on before the Derby.” Denmark says people really get into the spirit of the Derby, and get dressed up with fancy hats: “And they want mint juleps and all that.” She says not only are they expecting standing room only for the Derby, but they have a state bowling tournament going on at the same time, so parking will be at a premium.
