Agree with the author on everything except the kleenex. I carry an actual lens cloth in case its needed and only as a last resort. I started using lens caps on all by the nicest of days, they do an amazing job of keeping the dust off on even dry days tempting you to wipe the lens clean. Coastal sword fern spores on a nice day can get overwhelming, if I'm busting brush off trail I like to put the lens caps on.
One thing he didn't mention is buying a scope with a wide field of view (FOV) in the first place. An amazing amount of variable powered hunting scopes have really small FOVs. I didn't know about this for a long time, my longest kills were on a couple pronghorns in the desert and was happy to have my scope cranked up 18-20x... but those hunts are rare and an exception and hunting coastal environs even eastern Oregon environs most shots are under 100yds I was getting frustrated getting a fast close in sight picture even on the lowest power. Once I learned the cause I bought a Leupold with a 38 foot FOV . The only downside is they cost more.
