Departed Markham around 9:30AM stopping for gas and some last minute groceries. Followed Hwy 401 to Belleville for a stop at Walmart to get an inverter for the RV so we can charge laptops and batteries while driving. Had lunch at McDonalds while we where there and then headed off towards Montreal and Trois-Rivieres. I had programmed the GPS to take us to the intersection of Hwy 40/55 to keep us on the North Shore of the St. Lawrence and it ended up thinking it needed to have us do a U-Turn to get to that intersection. During that detour we discovered a Parks Canada site called des Forges-du-St-Maurice, the site of Canada’s first industrial community. It had unfortunately already closed for the day but it looked interesting so we might come back to it on the way back. Walmart has a policy of allowing one night camping at many of their stores, so once we once we got back on Hwy 40 we phoned the Walmart in Beauport to ask whether we could spend the night in their parking lot. No problem. We finally arrived at 8:40PM and had dinner. By 10:30PM, there were a total of 9 RVs in the parking lot, including one with Swiss license plates.
