How to memorise a pack of cards

I managed to memorise 37 of the 52 cards (numbers not suits) on the way in to work this morning. That's about an hour journey.

I'm quite pleased with that - although there's a long way to go to get to 52 cards, then add the suits then get it down to 5 minutes!

My first 4 points on my journey were, my bed, Max's bed, Lauren's bed and Zach's bed.

I have found that if I assign numbers to Gab, Max, Lauren and Zach it is more powerful than assigning to their beds - I guess it is obvious. But then I can also place them in other places on the route. It cross references numbers and enables me to re-use my strongest memory place holders.
