Hi Euroka, thanks also!!!!
I really think Leiden is a beautiful city, it's like small Amsterdam with the canals and stuff
!!
But the biking? Where did you go? 
It's all so flat that it never really mattered

but I remember cycling out to Noordwijk aan Zee for the afternoon.
Thinking back, there was never much room for tennis courts

but I suppose in this day and age there are indoor ones around now
