So I started the caching spree in Radnor and passed through the towns of Bryn Mawr, Haverford, Ardmore, Wynnewood, Lower Merion, and Roxborough, i.e. right through the Main Line. The caches were mostly pretty simple. "Concept" was interesting because it was full of yarn and letter beads, which the cache description suggests you use to make words to hang on a nearby tree. There weren't too many good letters left but I was able to make "PUPPY" from the remaining letter beads and I hung that on the tree.
At the end of the day, I was 6 miles from Philly and 9 miles from King of Prussia, so I went to SMD Philly. I parked in Philly Chinatown and took a short walk over to Field House, the sports bar where the event was held. With over 200 attendees, the place was noisy and packed. They had a projector and big screen set up to display a real-time feed of smdphilly tweets. About an hour into the event, they started a quiz and used that big display to see who answered first. Overall, this event was an interesting experience, although rather crowded. I think I'll pick a less-crowded suburban location the next time they have a multi-location event like this.
I didn't fancy the overpriced sports bar food so I cut out of the event a bit early and went to Banana Leaf, which was only 2 blocks away, and had chow kueh teow.
