About

Raterie située dans la région de Mons-Borinage (à proximité de la frontière française).

Mes projets principaux sont le devil (descendance de MIL Riley & MIL Noname) et le capé (descendance de ReBas Daphné & VIC Socrate. Je travaille également les familles de mes rates de coeur (descendance de MIL Cléo, MIL Darla et PEX Gazelle).
