Hah, suntiger, we are in fact doing a puffin boat! DS (who's 4) is really into puffins thanks to watching the children's TV show Puffin Rock. It's Irish and totally adorable: https://www.imdb.com/title/tt3590338/
Elizabeth P -- I think the weather was the same last summer when we visited, ridiculously hot and humid. There's a good chance of rain Sat/Sun, or that's what it said yesterday. Puffy is perhaps a misnomer; this is a Nano Air. It's a smidge warmer and lighter than a fleece, and more breathable than a puffy (the back and sides are a sort of waffle knit). I upgraded DH's and my fleeces to these during one of Patagonia's big sales. I"m not sure I'd pay full price for one, but we are definitely getting lots of use out of them! And like Rachylou, I ALWAYS need a puffy.
L'Abeille and Mainelady -- Yes, I'm happy to bring long pants and long sleeves even if they don't get worn as much. Like Angie, I'm better in heat than cold, and I like my sun protection. The hiking pants and long-sleeve shirt are super lightweight, and I like to have them for any trip where there might be ticks or other biting insects. Last year we did this trip in mid-July, and there were both black flies and mosquitoes. Oh, and tote bag is already stuffed in the car, so it didn't make it into the packing pics.
The funny thing about car camping, for us, is that we haven't really bought car camping gear. So we use our backpacking gear and it all fits into one large backpack. We got crazy this summer and bought a pair of folding camp chairs. Maybe in a decade we'll have a portable grill and a plug-in cooler.
Style Fan -- This is our second time driving the Maine/NB coast. There are so many gorgeous places to stop, we have a totally different itinerary than we did last year.
