Combination of public transport and scabbing lifts but it changes depending on placements. Can be as far as 65 miles or as close as 20min walk. Still to get allocation for May to Feb but as I’ve had most of mine up to this point close by then usually they punt you out to the sticks afterwards.
EDIT: I’m sure some people will say to cycle but it’s just not practical. Aside from carrying books I also need to take a full change of clothes and shoes, plus there aren’t secure areas to lock a bike or showers generally. Some sites it will be an option but those are generally (and annoyingly) the places I wouldn’t drive to anyway.
