The Blue Trail is easily accessible, is great for hiking/biking, and has some great views across the lake.
Here are links to the official park site & to a trail map:
This cache was sort of an afterthought thus the #2(a). We had planned out where to place the caches using the map on the MCP site not realizing that there are many side trails (the above map is actually better). As we were walking out, we noticed that we weren't on the same trail that we came in on and this afforded us the opportunity to get one more cache in. More is always better.
To get this smiley you'll have to look for the toothless grin.
Hope you didn't drop your pen.
