I have some general questions about the Jock River. I've heard it is canoeable, but am just wondering what it's like. I moved to Richmond last October, and it seems pretty tame.. looking at it, I'm not even sure which direction it flows.

I actually live right across from the canoe launch on York St. so often see trailers of canoes with people heading out for trips. Where do people generally tend to travel along the river? Is it a trip that can be made both ways (ie: no huge rapids that would ruin a leisurely trip back)?
My father in law is giving us his cedar strip canoe that he built a few years ago. He never uses it.. Unfortunately, it's not getting here until late August (it's coming up from Nova Scotia).
However, if there are actual rapids, etc. on the Jock, I'd like to pick up another canoe. Preferably, I'd like to pick up something relatively cheap (~$300 - $400), even if it is a fix-er-upper, just for exploring and the odd camping trip.. any info on where to look for something like this as well would be greatly appreciated.
As another note, I'm looking for plans for a canoe shelter. My garage isn't really big enough for canoe storage and the car, so I'm looking at building a shelter in the backyard.. I've got a few ideas in my head, but plans always help.
Happy canoeing..
