Should we list free things to do separately?

We have lots of great things going on for over 50s ,and to do with grandchildren or younger relatives and friends, but should we make a category under 'What's On' for free activities? Some of the great things we look at do seem expensive, and if we want to go out on a whim, would it be useful to have ideas of places to go where we don't have to fork out the fivers ? I am just musing on this before asking Gransnet HQ, so any response would be very welcome. Enjoy your day!
