Merry Christmas, Bing!
A lot of people fish muskies up here. I'm not one, as I like to eat fish I catch and muskie hunters are all catch and release. I think the "fish of ten thousand casts" with a fly rod you'd wear your shoulder out before you ever caught one. It would be fun if you did, though! I think fly fishing for smallmouth bass would be more fun and more productive. Pound for pound a smallmouth has the most fight of any fish we have in the northwoods. Smallies are really curious fish. I tell people that if they're swimming in a lake that has smallmouth, they're being followed by the fish. People think that's a crazy assumption, but they follow me when I'm snorkeling and scuba diving. While diving they'll come up within touching distance. I think the sound of the bubbles attracts a lot of fish.
The only way to know if the ice is safe is to test it. For several weeks my neighbors have been going down to the lake, walking out and drilling holes in shallow water. 4" is plenty to hold a man, 6" for a snowmobile or ATV. My Ranger is heavier than those so I wasn't going to risk it until we had 8". We've got plenty of ice now and soon we'll see guys driving their pickups out. Need at least 12" for a truck.
When it's really cold and we're "making ice", the ice will pop as it expands. It can be a bit unnerving to be sitting out there and it's loudly popping. But especially a little later in the winter we know we're not going anywhere. We'll end up with 2 feet thick ice on the lake.
I read an article over the weekend about how there is very little clinical trial and testing for medicinal uses of MJ because it's a Schedule 1 drug. There is only one lab approved for growing MJ for research and people say the product they produce is garbage, nothing like people are growing these days. There was legislation to move it from Schedule 1 status a year or so ago, but Attorney General Sessions had it shot down.
The arthritis in the knees sounds painful. Our club Pro's wife suffers like you. She recently had a laser treatment that was to break up the arthritis in a non-invasive procedure. She said it helped. I haven't seen her in a while and now am curious as to whether the effects were short or long term.
It's going to be a quiet couple days here in the office. A lot of folks taking the week off.
Take care and keep on biking!
