Starting with last weekend:
Very interestingly, I met another Schabel at the conference - a retired german-american University Professor named Hans. I've only met one other Schabel in my life, and that was Dad's cousin. We had a lot to talk about - there could be a distanct relation connection. 8 generations ago my forefather Hans Schabel moved to Denmark and started a locksmith business. Funny!
Following the conference Hans and a fellow american David (who started an edible insect educational business) were interested in seeing more of northern Thailand for 2 days, so we hired a car and headed north west, to a cave lodge 15km from the Burmese border. The karst scenery is spectacular (I headed here on my MHS motorbike adventure) and we visited Tham Lod. We saw thousands of cave features, thousands of bats, a couple of 2,000 year old teak log coffins and cave paintings. The absolute highlight though happened when we left the cave at dusk: 300,000 (odd) swifts flew back in the cave in large spirals to roost for the night. This nature spectacular lasted for almost an hour (black specks in the twilight photo below). We stayed in a bamboo bungalow and went for a valley walk the next morning, stopping frequently to seek out bugs and discuss other natural science phenomena. I learnt a lot!
