There's going to be literally hundreds of shiners who work out of more than one base. A place, for example, where they setup, have their main round, the place probably where they learnt the ropes; then when they go and stay at the long-term girlfriends place who lives 150 miles away they've started to develop a round there. Easily done, most guys in that kind of situation have probably reflected on the viability of such a set up.
