I'm stuck in a cycle that reminds me of the old poem about a nail, a shoe, a horse, a knight and so on.
I'm laying the first loop of track and have run up against the first of two waterways to be bridged. I can't run the track as the bridge needs to be installed. I can't install the bridge because I have to get the stream painted before putting the bridge in. I can't paint the creek as its not sealed yet...
And we wonder why it can take so long to get our layouts completed. Still making progress, just a little slower than I'd like.
