Yeah, I guess you could go through the Snake Creek lift bridge, or go farther south to Channel 5 (which would be like sailing almost half of the Steeplechase).
Snake Creek is closer, but make sure you have a way of contacting the bridgetender -- and watch out for the current. If it is going from Bay to Ocean, you may not have a choice about waiting for the bridge to go up (have an anchor ready). And if it is going from ocean to bay, you might have a hard time getting through the bridge (have a paddle ready). <img src="http://www.catsailor.com/forums/images/graemlins/tongue.gif" alt="" />
