A minor update

I've taken the time to make a couple of minor enhancements:

  1. The links to the map on each card page now center the map on the card location and zoom in a bit.
  2. I've added example links for many of the cards discussed in the collecting section.

I've also been adding a steady trickle of cards to the site. I'm on the way to 400 cards now which is great as this is starting to become a representative sample of Stuart's work.
