Refer to the current Denver sectional excerpt around the US Air Force Academy. According to the note printed on the chart, what does the FAA suggest a pilot do near Alert Area A-260?

Why: The chart prints this exact advisory next to Alert Area A-260: "Pilots are requested to avoid flight in the vicinity of the USAF Academy due to intensive student pilot training and parachute jumping, surface to 17,000' MSL. See Supplement for hours of operation. Suggest flight east of I-25 at or above 9000' MSL." It also gives an advisory contact: Academy Tower on 124.15 MHz.

• An Alert Area specifically flags unusual aerial activity (here, concentrated student training and parachute jumping) that general Class G airspace does not — the chart's advisory exists precisely because extra caution is warranted, not because none is needed.
• Alert Areas do not themselves require a waiver to transit — the chart's note is an advisory asking pilots to avoid the area or fly a suggested routing/altitude, not a regulatory waiver requirement.
