I brought a book and my Game Boy Advance to keep me company in Cabo.
The book was Jupiter by Ben Bova. I read the whole thing in a week, which is record time for me. It was pretty good! I’d recommend it.
On my Flash Advance cartridge I had Super Mario Advance 2, Castlevania: Circle of the Moon, and about 30 8-bit Nintendo games. I actually wound up playing NES games 99% of the time. In fact, I managed to play MegaMan 2 from start to finish during the trip. They just don’t make ’em like they used to.
