[78attendees] cave biking

[Jari Arkko <[e-mail]>]

There are some "caves" near Maastricht. Or really, man-made historic 
tunnels, they were used during the war hiding out, for instance. These 
days they organize tours and various other activities over there.

I would be interested in doing their "cave biking" tour. The idea is to 
follow a guide around the cave system on mountain bikes for an hour and 
half. I expect it to be a rather leisurely ride, nothing extreme.

However, their tours normally run during the day when we are all 
meeting. But if we had a group of ten we could have our own tour at 4:30 
pm tomorrow Friday. If you are interested in joining such a tour, let me 
know. We would leave the hotel 3:30 pm. The cost is 25€ + your share of 
the two-way 25 min. taxi ride to the site. Its somewhat chilly in the 
cave system so you may need a jacket or similar.
