<br>looked for an answer (of course, this may very well be a completely<br>ridiculous question, and I could save myself the feeling of stupidity if I<br>just opened a few sforim and looked into it, but so far I haven't made the
<br>time).<br>So, does anyone know why we wait to say V'sein Tal Umatar (which I always<br>understood to be so that the olei regel could get home before the rain<br>starts), but we don't switch to V'sein Brocha until they've already been
<br>oleh regel for Pesach? Shouldn't we back up the switch before the travelers<br>set out?<br>- yonah sears</span></p>
