OV where you at ? if its warm take her out and just have a walk , youd be surprised how good in can be in dates ... or if you absolutly have to do something ... maybe something more original ... take her horseback riding ... not brokeback mountain...
60$ is enough man ...
meeting at a coffe and having some 3$
walking around/skating.wtv activity ... 0$
going to dinner 40$
buying some drinks after ... around 20$
showing her you dont need to lay out the $ to have a good time and she knows you can be cool even if its just walking ... priceless ... for everything else theres .
