I borrowed an additional tagalong bike (thanks Dave and Michelle!) so now the three kids and I can go bike together (and make Laura look lonely on her bike :-)
We rode into Ft. Stevens and over to see some of Laura's family who were camping. So we rode this contraption for about 6-7 miles. It's fun, but not very stable. The kids like to lean to see around me, and I was concerned for the safety of people passing us going the other way on the bike trails. Everybody came through it well, though, and it was fun getting honks, pointing, and waves from people as we passed!
