Birch spore rhinitus

9°C, clear, icy at night.
Sneezes- but no cold. It’s just like hay-fever so I blame tree spores.
The campsite I had in mind has not opened their canoes, said because the water is too cold. Really? I can sometimes see people in boats, breaking thin ice as they go. Go on, let me go out.
I have a three-season sleeping bag, with a bivvy to pull over if it’s still too cold in the dead of the night..
So, this change of plan- a different site with wood burners and better shelter from the dry, bitter northerly wind.
