A busy weekend for the Highwood Mustangs boys and girls rugby squads with the Clearwater Cup 7's Tournament starting Friday, May 12, in Calgary.

The Mustangs ladies have been unbeatable lately, winning the Mustangs 7's last weekend, and scoring a big 55-7 win over Rundle College Wednesday, May 10.

However, Coach Bill Young says don't call them "invincible" just yet.

"We can always be stopped. You just go back a week where we were humbled by HTA and their program. That wasn't an easy one to deal with."

The Clearwater Cup runs Friday through Saturday, May 13, with 64 boys and girls teams taking part at the Calgary Rugby Union on Sheppard Road.
