Just returned from a two week vacation driving around Tasmania in a camper. I was scared of having my horn flogged so I took just a mouthpiece and buzzed my way around the Apple Isle. This is the longest I have gone without a horn in 28 years. To my surprise, I have come back refreshed and I seem to have remediated a few minor problems that have been bugging me for years. I have neglected mouthpiece work for a while. I am going to buy another mouthpiece and keep it in my pocket so I can do a bit of work where and whenever.
While my endurance will be down a bit, I don't think it will take me long to get back in shape.
(By the way, Tasmania is beautiful if you get the chance.)
