All the coastguard or police are going to do is tell you to get off the river and go home, to which you can reply that that's exactly what you're trying to do <img src="images/graemlins/cool.gif" alt="" /> While I still think you'd be better off on foot or two wheels, if you're serious about heading down river, this boat might be a better idea than a zodiac, much lighter and no inflation time/gear. But unless you're willing to keep an outboard motor in your truck, it doesn't seem like it'd be worth it to me.
