TringCon XVII and XVIII - October 2008 and April 2009
TringCon comes in two bites each year - the first Saturday in April and the traditional first Saturday in October. The hall has been booked for both dates, so all you need to do is to put them in your diary and be there - but please let me know you'll be coming so that the catering matches the attendance. I'll bring some games, but you are advised to bring anything you'd like to play. I suggest you put a slip of paper with your name in each game you bring. I will also have a number of games on hand for you to buy, should you feel the need to expand your collection.
There is no specific format to the day about what gets played when and what, indeed, gets played. That's entirely up to you. The last event saw a variety of games on the tables, including Antike, Around the World in 80 Days, Coloretto, Khronos, On the Underground, Phoenicia, PitchCar, Power Grid, Puerto Rico, Tacara and Vikings. Your entry fee also gets you a buffet-style lunch and tea.
