Today on the highway, we were driving north just leaving Calgary, when I look across to the southbound traffic and see a yellow Ferrari F355 Spider. I was like "Holy shit, a Ferrari!" I got butterflies.

I had just turned my camera off about 30 seconds before we saw the car though, so no picture.
Then, I saw a Mercedes-Benz SL55 AMG (silver roadster) in the Boston Pizza parking lot, and I was planning on taking pictures of it, but first my dad needed to buy some rope. He was 20 minutes inside this store buying this rope, and by the time we got back to BP the Benz was gone...
Before both of these sightings I saw a BMW M3 Cabriolet in the mall parking lot. I had to go into the mall for a few minutes, then rushed out to get some pictures of it. Luckily it was still there when I got back, so here they are.
