This is the expanded version of the book being sold in the Trading Post at Camp Arcadia. This book has 152 pages; the one in the Trading Post has 80. That's really the only difference. Oh yeah, that and this book does not currently have any 2 page spreads. I thought it would be nice to have a choice - more photos, or a less expensive book. However, this one has about 70 more pages for about $10 extra dollars. You decide! Enjoy! I know I loved making it - I hope you enjoy looking through it and counting the days until you return...to that place on the shore....A-R-C-A-D-I-A !!
