Kanuga is big fun. It's a great descent in one direction and a challenging climb if you go the other way. And Firetower is OK. I usually make a lap out of going up Firetower, then turning right on Kanuga and then left at the bottom to go around the lake. Take the Pepsi trail back up and you can go all the way to the road or turn right up to Kanuga and get another lap in.
