Demonstrators rallied once again late Wednesday night in an effort to prevent a convoy with parts and materials from reaching the Daniel K. Inouye Solar Telescope under construction on the summit of Haleakala.

This time members of Kako‘o Haleakala, the group organizing the protest, and others gathered at two locations — at the Central Maui Baseyard near Puunene, the anticipated staging area for the shipment, and at Crater Road in Kula, the beginning of the final leg of the journey to the top of the mountain.

More than 50 flag- and sign-waving demonstrators were at the base yard on the Mokulele Highway as of 8 p.m., a few hours ahead of the planned convoy launch. They were chanting and marching back and forth across a crosswalk at the entrance of the base yard.

Maui Police Department officers were also on hand Wednesday night.

Twenty demonstrators were arrested July 30 at the base yard in the last attempt to block an oversize shipment of telescope parts from reaching the summit.

This is the third time the group has attempted to stop a telescope shipment. A convoy of oversize trucks was halted by demonstrators at the base yard June 24 without any arrests.
