One thing many of us frequently do when traveling -- whether by RV, car, or plane -- is take a computer with us so we can continue our 'putering'. Most of us also connect to a public wifi network, whether it might be in an RV park, hotel, airport, or restaurant. There's risk in doing that. Read here and here for some examples. You'll note that using a Virtual Private Network (VPN) increases the security of your internet browsing significantly. When I'm traveling I plan to use the Opera Browser. Why, you ask? It has a free, built-in VPN. Read a review of Opera here.
I've been trying Opera out, like it fine, and have noticed no significant slowdown in accessing the internet for browsing or emailing by going through Opera's servers. If you plan to do some traveling, and would like to try Opera, you can download Opera here. Note that if you want to use the VPN feature you'll need to go into settings and turn it on. Then you'll see a "VPN" icon just to the left of the address bar.
Opera is free, fast, and includes a VPN. What's not to like?
