Should "future" experience (for example, experience during the summer between application submission (Sept/Dec) and the start of the fall semester) be included on resumes? If so, how should it be listed?

Also, I volunteered with an organization that monitored sea turtle nests during nesting season (May - Oct) on weekends and school breaks -- what would be the most comprehensive way to date this experience?

Should references be included on resumes? Although some schools allow resumes up to two pages, the personal statement add on course to stick to one (references are currently on a second page). Also, the section titled "What to Cut" includes the phrase "references available upon request", which gives me the feeling I should not include references at all on my resume. Are recommenders on LSAC considered to be the same as references on a resume?

Thanks!
