Cars. Wheels. Shed. Tools.

Cars - He will sit in the drivers seat totally amused for hours. Last night I was trying to get him out of the shed & he hugged the car crying!

Wheels - will try to undo the bolts for ages. Likes to just stand there & hug them

Shed - If DH goes into the shed, DS will stand at the door & scream til he gets in. (Our garage off the loungeroom, lol) Problem is that DH is usually going in there for a smoke

Tools - Compressors etc. They are absolutely fascinating.

Oh & he barks & growls at everything, lol.
