A lot of our members do this on the 6th and 7th at Schuylkill CC. Mostly walkers. They hit a tee shot on the par 3 6th to the green, then walk over to 7 tee and hit a tee ball which is fairly close if youre playing the tips. Then they finish out the par 3 and walk to the 7th fairway to keep playing. I found it odd the first time I played with a group that did this, but it works okay. Its never busy enough to cause a problem.
