Well you've all been very busy since I've been away but I saw this the day I left and didn't have the time then to work on it.
Just finished it now and it is truly a workout! I got caught a few times here and there, the yellow gate

and the tramping moves to get to the spheres caused some problems and then setting up the order of things and determining what to eliminate took more time and more restarts but I'm happy to say the gold is mine!
Thanks for the welcome home Michelle!
