This was a fun project. I built it for our local county fair and it was a hit, I won an award.
I used all cedar 2x4 and 2x6 lumber. I used pocket hole screws. and glue and I used carriage bolts to make it stronger. I used Thompson Simi- transparent stain/ sealer in a Honey color for the finish. It will last a long time and will be perfect for all kids,
