Mt. St. Helens is near where Steve's Mom lives, so I'll bet you will get to go there. If you fly on a clear day, you will see it from the air too. It's on the flight path to the airport here.
They can take you to one of the mountain passes too............about an hour's drive to the ski areas............lots of snow. We are surrounded by mountains here............Cascade range on one side and Olympic range on the other side of us, so you will see snow............never fear.
The needle is in Seattle, about 20 minutes South...............no problem. They will probably take you to the top.
