Hienot kuvat Joulukuun reposista ! Hyvin tuo Samyangi näyttää piirtävän. Hyvinkäällä samoja reposia jahtaamassa hieman tuulisessa ja kylmenevässä illassa.

Kiitos Kari. Kovat tuulen puuskat riepotteli kameraa,niin että piti toisella kädellä pidellä kiinni.Parempaa paikkaa etsiessä,jälleen kerran,pilvet peitti näytöksen! Pohjoisen taivaskameroiden kuvia seuratessa,tuli taas kaipuu Kilpisjärvelle!
