Oh for crying out loud. Is this not an internet forum about RVing? Are the OP's posts not about RVing? Are we really going to create rules where none exist because some people are (for some unknown reason) irritated because the OP is having fun telling others about his travels?
So all being equal, the mod should create (if he/she has the power) a new forum topic called Trip Reports, or similar, then those who are so upset can be made happy because they don't have to notice a new "Day" topic.
If not possible, then I see nothing wrong with it. If you don't like it, then start a thread about tires, how other people do things differently, dog poop, or how it's stupid to wear gloves while dumping, or why your mods are better than anyone elses. Maybe a rant thread dealing with people who post trip reports.
I've seen etiquette posts about dump stations, campground behavior, how not to park at a rest stop, how to act at a gas station, LT vs ST tires ad nauseum, but trip reports?
A recent thread wonders where all the old time posters on RV.net have gone. Well, you have your answer.
