How was touring the Niagara region? I was planning on figuring out a route from Toronto to Niagara and doing some wine country touring during that trip (for my bike club). I've ridden around Niagara-on-the-Lake a bit and loved it and it seems like from Toronto to Niagara would be a fairly flat ride so I wouldn't have to grade the trip as too hard and could get some newbies along.
We'll have to keep in mind to bring some extra space for the wine though!
