You can launch at the Coleman Powerhouse near Potlach on a minus tide if you have 4 wheel drive. When you get near the bottom of the ramp "dog leg" your trailer away from the wash pile. I like the south side and drive out where the springwater flows. My 22' Intruder launched right in front of a 24' Bayliner that had to wait out the tide 'cause he high centered off the end of the ramp. Always take a look at any ramp before you back down it!
