I have several avocations, but too little time to make a nice page about them at the moment.
Besides the sports listed below, electronics and computers have been my hobby since childhood.
Concerning sports, I practice several ones in a recreational way, mainly skiing, snowboarding, bicycling, motorcycling, horseback riding, and scuba diving.
I sometimes use my motorbike as a transportation to geographically close-lying conferences, e.g.
in the Conference Center of Academy of Sciences in the Liblice castle.
Hubertus ride in the beautiful autumn nature is always a very nice experience.
This is a picture from a bicycle trip with both children:
And a year later, Stepan already sits in the child seat;
surprisingly he is able to sleep in the child seat during
a trip on unpaved roads :-)
This is a picture from a wreck dive at Key Largo, FL
This is me with a grey nurse shark in Sydney; this dive was certainly a more exciting option to the default conference excursion.
are some underwater photos made at the Great Barrier Reef near Cairns and here
are a few ones from Key Largo, Florida.
