In addition to my Criterion and Mark Provost's Lifeliner, Bayshore Ambulance sent one of their Dodge Sprinter ambulances, and Royal Ambulance participated with a late model Ford based ambulance. The relay received over $76,000 in donations over the course of the day. This is down from our peak of $130,000 a few years ago.
The night before the relay Mark replaced my Federal PA-100 siren with a PA-200. The end result was a MUCH louder siren; 100w per speaker vs. 65w. When used in conjuction with the B&M Super Chief, it produced a real wall of sound.
