Kelly - great update! Thanks.
Surgery on the lower bones/joints often times goes a little slower than one would like. The joints in the lower half of our body support the weight of the whole body, so you want to be sure that they're working properly before you start stumbling through freestone streams and the like.
I hope that the doc says: "go"; but if he doesn't, stay with his advice. The fish will still be there when you're fully mended and I'm sure that your wife appreciates the little things that you can do around the house while you're home-bound
