world CLIMBERS party
There are many crags that You can't reach with public transport and, at the same time, where You don't need a car.
For example Rodellar.
If You want to go climbing 20 days in Rodellar, it's not the best solution rent a car that You'll never use there ...
So, just ask for a ride in 9b party !
In other words: use 9b site as a car pooling and carsurfing / vansurfing tool.
If You share costs and/or return the favour where You have vehicles, for sure there are foreigner climbers willing to give You a ride and/or share with (or rent) You their vehicles.
Just use the "search members box" to "surf" and ceck 9b climbers profiles.
