The Welsh party conference season gets underway today, with Plaid Cymru meeting in Newport.
Like the other parties who'll gather this month, Plaid's emphasis will be very much on May's local council elections.
With so much political uncertainty since the Brexit vote, the elections are an important test of the parties' standing with the public.
They're also a one in five year opportunity for voters to pass judgment on their councillors.
Plaid Cymru doesn't have overall control of any local authority but has forged alliances to secure the leadership of Gwynedd, Conwy, Ceredigion and Carmarthenshire.
Plaid's hoping for gains in May. The top targets are Caerphilly, where the party lost power to Labour five years ago, Rhondda Cynon Taf, which it ran between 1999 and 2004 and Anglesey, where Plaid's already the biggest party but independents run the council.
Of the councils it's defending, a particularly hard fight looks likely in Carmarthenshire, where Plaid only took control after the independents switched their support from Labour.
Labour's fighting back, with most of its Carmarthenshire councillors opposing the decision to make Ysgol Llangennech an entirely Welsh medium school.
Plaid's leader, Leanne Wood is expected to use her conference speech to point out it's Welsh Government policy that more schools should teach through Welsh. She'll suggest that Labour council candidates should either back their ministers' strategy or stand on a different ticket.
But the main emphasis of the speech will be on what Leanne Wood says is Plaid Cymru's mission to rebalance Wales.
She will claim that the Welsh Government has made the same mistake as the UK Government and cultivated an “overheating centre at the expense of everywhere else.”
