We liked the campground (quiet), weather (warm) and company (Jim and David) so much that we decided to stay another day and just relax.
Jim, David and I rode to Grand Coulee Dam to attend a tour of the dam. Lots of information was provided, only a few of which I remember. The dam is the biggest concrete structure in the U.S. Water from the dam is pumped into an aqueduct that irrigates 671,000 acres in central Washington. At peak output, the electricity generated by the dam can power both Seattle and Portland :-o.
After the tour we spent the day hanging out with drinks served at Jim’s RV later in the afternoon.
