When I went to TMP I crossed into Ft. Erie, and hopped right on Garrison Rd (the other 3), and took that most of the way there. That sends you straight through Port Colborne but other than that it’s a pretty nice drive.
I’m not sure if I’ll just do that again, or follow the google maps directions that send you up the QEW and across 25 to 525 to 23 to 3.
Which ever way I end up going, I’ll probably go the other on the way back.
