That means that you are still using WiFi, not campground WiFi but WiFi from your laptop to your phone or separate hotspot.

No getting around it unless you use a physical cable between your phone or hotspot and laptop. But the data on the internet is the same anyway and it is really easy to "sniff" if so inclined. Whether in the air or on the net you are still relying on HTTPS.

Along this same line, how can I boost my reception? Do I need a 4G booster, a Wi-Fi antenna or something else? I work online and there are some places with poor coverage. (Hocking Hills, OH is one.) I am on ATT and use their Mi-Fi for my secure network. I also have Wi-Fi in my vehicle via On-Star and hot spots on my phone and iPad. However if the reception is poor, these don't work either.

In both of your cases, you're asking for a cellular booster. The biggest trick with a lot of boosters is that the area that benefits from the booster is usually quite small (12-24" around the interior antenna). There are some setups, though, that boost a much larger area (look at the weBoost 4G RV edition). This gives you a bigger boosted area (which would cover your iPad wherever you are in relation to the RV and possibly even your truck's on-star.

Campground Wifi's are notoriously "targeted". Do not trust them for anything important. We use a Jetpack hotspot from Verizon or the Apps on the iPhone using the LTE service.

Me being a web developer/programmer, but not necessarily security minded...

Can someone explain exactly how encrypted traffic can be intercepted and monitored?

Anything that is "important" is going to use HTTPS/TSL. You have encryption happening from the moment you send it from your browser to the server.

Now, your laptop is potentially more vulnerable being on an unknown network. But that are your files at rest- not your online activities.

So, can anyone tell me what the concern (in technical terms/papers/articles) is with secure web sessions over HTTPS/TLS?

Agree completely, but it is a normal concern from those who don't understand digital, protocols, how HTTPS or HTTP or any of this stuff works. Sort of concerns from the analog world. Of course you are right and I can't wait to see if anyone answers your question.

IT guy here and security specialist. No free or public Wi-Fi is safe. Not at a campground, hotel, hamburger joint, our your dentist's office. I don't really trust any network that I didn't setup myself. Take the advice and get yourself a private hot-spot and run as much protection software as you can on your phone and PC. And then think twice before typing in anything that you aren't comfortable with the whole world knowing.

It's not encrypted when you are typing it in. It has to be unencrypted again at some point. The common encryption protocols can be cracked surprisingly easily. They can gather the encrypted data and crack it at their leisure. If they think that you have something worth the trouble they can get it. All you can do is try to make it more trouble than it's worth.
It's actually easier for them to just ask for the credentials than crack them. You have to be alert to the state of your machine and keep your software up to date. They want SS numbers, CC info, etc. They gather this kind of info and package it into bundles. You can go to their website and buy a bundle of 1000 CCs info for $100. Make sure that they have to work for it.

The time hat it's unencrypted is going to be within the hardware of the machine- from the keyboard into memory and then encrypted by the browser. It never leaves the machine that way.

After that, as I said - I haven't been up on encryption protocols, but I do know that TLS is supposedly significantly more secure than SSL that it replaced.
