SW Makers October 2017 Eaton Meeting

..It's starting to feel like a summer might actually happen here in the SW of WA.  We skipped the last Busselton meeting due to the long weekend, so it seemed like we hadn't caught up for over two months.  There was lots to catch up on.

Here are some links to things that where discussed:
