Help with Fieldtrips

We, as a first grade are struggling to meet our financial goal of being able to pay for our last field trip to Hill AFB.  We were hoping to be able to go there and also have the Nature Center come into first grade.  With the lack of donations toward field trips we are at risk of not being able to fund the transportation on the field trips.  If you have not paid your $10 donation for field trips and are now able to, we would be so grateful for that help.  We realize that not everyone can, and that is okay, but if possible it adds a lot to our students learning.  Thank you in advance for any help that we can get in this area.
