Great thread idea Bookwrmmom!!
My GAL activities are still restricted to cheap/free due to finances, however there are plenty of options:
1. check online voucher schemes for deals, such as 1/2 price tickets, spa treatments, manicures etc.
2. load up your mp3 and go walking. I have a dog so this has helped me get out daily and explore some gorgeous parks and hills.
3. take up an evening class
4. long phone call with friend
5. meetup.com has loads of different groups and everyone is super friendly
6. visiting local museums, National Trust properties
7. get involved with an arts group- a local theatre, a community arts centre, etc
8. volunteer
9. check events section in local newspaper
10. check out locak library/bookshops, explore sections you wouldn't normally bother with, eg. poetry, arts and crafts, science fiction, crime/mystery.
