I should update this. Knee surgery went well, but it aggravated the slipped disc in my lower back. Now I waiting for surgery on that. Hey things wear out. If you bought a F-100 in 1947, by now you would probably need new ball joints or a tune up. Well the same thing is going on with my knees and back, 71 years after being born, they are wearing out. Got the tune up - a stent in my heart three years ago. Dennis, I am going to try and get up and see you in the next week or two. Not going to bring cannons yet. Besides talking to you about a mile shot, I want to talk to you about test firing a blank load. The Load consist of a pound of black powder and 25 lbs of flour. The Flour might leave a white spout on the ground, a large white spot that should go away with wind and rain. I have been talking to model rocketry guys about telemetry, mostly to locate the ball afterwards. They have came up with neat ideas for me on mounting a locator beacon and a camera.
