Tips
- 💡
How do I find out if a library event requires registration?
Check the library's event page before you go — some drop-in programs fill up fast, especially storytimes and craft sessions.
- 💡
Are farmers markets stroller and kid friendly?
Yes! All the local farmers markets are open-air and easy to navigate with little ones. Go early for the best produce and shorter lines.
- 💡
Can my dog come to Paws to Read events?
No — Paws to Read is for kids to read aloud to a certified therapy dog. The dog is there; yours stays home.
- 💡
Are the library programs really free?
Completely free — no library card required for most drop-in events. Just show up!
