The way points of this bicycle route:
You could use the Interurban Trail as an alternate route (pick it up under the freeway overpass)
Bike trail on sidewalk; look left just past the overpass for a route onto the Hwy 29 roadway; take the road or the bridge sidewalk.
To the left is a park/boat launch w/bathrooms.
Be Careful! Fast traffic, and you need to go down the hill, under the overpass, and turn left under the bridge for the bike trail.
You have returned using Colby Ave. (you could have also used the Interurban Trail from 44th to here.)
