Ignoring the horrendous M62 West, the hour journey crossing Leeds to LBA and the increasingly unpredictable M1 South to EMA for anyone South/South East of Leeds, there is a large bucket & spade population East of the A1 & as far South as Peterborough & North to York for whom DSA is the preferred airport.
