Need ideas to document a cross-country drive, MN to FL

We took photos of the Welcome to _____(state) signs and when we stopped at rest areas, some of them had local displays or art or even trails and we took photos there as well.

Play the license plate game. Keep track of what states you can click off. At the end, print out license plates, with thoughts on what you think of the license plate graphics? Which was your favorite design?

Keep track of how many Waffle Houses you pass.

I like to keep my DSLR in the front seat with me, set for action shots so I can get pictures as we're driving fast on the interstates. I like to get "welcome to ______" signs, signs for major rivers, stopped traffic (if unlucky enough to hit some), skylines of major cities, etc. Or just anything interesting along the way, especially the further away from home & what you normally see.

Other things I've documented include the movies that were watched (on the van's DVD player), XM radio stations we listened to, places we stopped to eat/fill up/potty break.

+ any music or podcasts you and/or the teens listened to; document the playlist(s) and favorites
+ games/discussions/friendly banter (or recurring friendly arguments?) that occurred during the trip**
+ movies/shows watched if the passengers have anything downloaded on their devices for the trip
+ do a page of "most/least" or "worst/best" -- for example: which state had the most and least # of restaurant/gas stops, most/least amount of traffic, most/fewest ticky-tacky tourist traps, etc., or best/worst food, best/worst billboards, best/worst things purchased at said ticky-tacky toursist traps (if you indulge, LOL), etc.

** For example, some of our favorite road trip memories come from some friendly recurring arguments and silly banter between cousins and siblings when they were preschool/elementary aged; likewise another memorable road trip (this time with teens to FL for WDW) happened just after a major release of Pokemon GO, so they were actively asking if we could please stop at particular places so they could get a certain character, LOL.

ETA: Yes, definitely any movies watched by the whole car on built-in DVD players; or games played on those screens as well.

One road trip we took DD's little beanie baby mouse and posed him for pictures in different places. Kinda like a Flat Stanley.

On our last road trip we kept track of how much we spent on gas and where we bought it (also price per gallon).

Also every area has it's own soda/pop and snacks. Take pictures and definitely buy them to try them!

I think the original idea was Barbara Picinic's (yes, it's in here thepicinicbasket.blogspot.com/2014/10/road-trip-mini-album-completed.html but I totally scraplifted her summary sheet to create an (almost) identical one for a similar trip and, I'll confess, have done one for each trip ever since!
(She actually did a tutorial for how to create it in PSE so I don't feel too bad about it any more!  thepicinicbasket.blogspot.com/2014/05/how-to-make-infographic-using-photoshop.html

elegantsufficiency love love love the bug splat count! LOL

I use Google.maps while I drive. Whenever you enter a new state, a welcome icon pops up. I try to take screenshots of them.

There are some really great ideas here! Thanks for sharing everyone and moretimeplease thank you for asking the question that I ought to have asked ages ago!

So many great ideas! Travel minis are my favorite things to make and I usually start with a page of stats. That summary page from above is pure gold! I can’t express how much I love it!
