Last weeks preparing my next travels this year. Half March one week to German Wadden Sea. 20 April - 5 May two guests from Vietnam visiting Netherlands, I am preparing their program. Combination of work (water management) and fun in weekends. Many flowering tulips during that period! Nature travels in SE europe: 17-24 May Bulgaria (northern mountains, coast), 24 May-5 June Romania (Danube Delta). Half June - half July Vietnam, HCMC. Project on water management. Later this year hopefully Filippines.
