I went to my brother-in-law today, he lives in Vienna, Ontario, a mere 50 kilometers from my house.
But I rode 182 kms to get there.
On the way back from his house to mine, I made a little detour from the usual way and found this little gem:
Maybe 10 kms long but lots of curves and elevation changes. Something somewhat hard to find in South-Western Ontario, where roads are mostly flat and straight.
Rode 235 kms or 146 miles, used 11.5 Litres or 3.04 US gallons for 48 mpg.
