Here are some my boyfriend actually came up with:

1. Coffee shop (try a local place rather than a chain for more ambiance/feel)
2. Dog Park (bonus if one or both of you have a dog to walk)
3. Picnic – could even be some cheap takeout in a city square
4. Skating (ice or roller). So what if you’re no good – show some vulnerability
5. Farmer’s market (stroll past the booths, buy a couple pieces of fruit)
6. Bowling (it’s not about the score, unless you both want it to be)
7. Trivia night at a local bar/cheap eats place. Impress him/her with your useless trivia knowledge
8. Carnival/State Fair – Popcorn and cotton candy aren’t all that expensive.
9. Zoo – because who doesn’t love cute little animals
10. Hiking – enjoy nature, pack some trail mix
11. Art galleries – if you catch an art walk night you can even get free wine and cheese
12. Local community theater
