Bikestuff from Saint Charles, MO on 3/21/2011 3:04:09 AM:
Here is the link to the bi-state transit. All its buses are equipped with bike rack so I would assume bikes are fine on Metrolink. I don’t know about your BoB trailer. You would probably have to disconnect your bob trailer before getting on the bus and metrolink.

From St. Charles you would pedal back (heading west on Katy trail) to hwy 364 (or Page extension bridge)
Take the ramp up to the Page Extension Bridge and cross over the MO river—this is Creve Coeur lake connector which is 3.8 miles paved trail. There is a roundabout at the end of this trail, and you have some options here.
Option 1: If you wish to ride all the way to the airport using this site direction then turn left at the roundabout then right to get on the rusted iron bridge (you can’t miss it). About ½ mile later you will see Marine Dr running parallel to the trail on your right. Turn right on Marine Dr as soon as you see it and you will see the hill.
Here is the “official” direction to get to the Katy from the airport http://www.bikekatytrail.com/airport-katy-trail.aspx You would have to do it in reverse. That means you would have to climb a big hill on Marine Dr from the lake with many vehicles (probably) line up behind you honking. There is no shoulder for you to pull over. If you successfully navigate to the airport, it would still be pretty tough to find your way to Metrolink station at the airport. People would probably think you are insane.
Option 2: if you wish to take buses to the airport Metrolink then go straight at the roundabout. You will pass a nice bar on your right before turning right. The trail will end in a few hundred yards and dump you to Creve Coeur Mills Rd. Take Creve Coeur Mill Rd to Olive Blvd where you need to catch a bus with possibly a transfer ticket to MetroLink.
