I took Maxi on this adventure. She's not getting out much these days, I feel bad for her. She did great, I think she can be a regular. No problem with the terrain, she ran as fast as I wanted to run - I was held back only by my own sub-par navigation. She did get in a tussle with another dog, but it was my fault, I tried to introduce them gently, but it didn't work out. She didn't growl at any dog at registration, which I consider a win. I'll have to buy a jogging leash for her.
As for the orienteering, I did my first Score-O which Jon provided advice on how to run it which I did follow. I didn't use the compass much, but the trails confused me to no end.
