For further trips with your girlfriend.....there is nothing better than fishing at night. Watch the sunset....smoke a bunch of fish....then seeing the moon cascading over the lake.
Here's a few articles I've found regarding this topic..... http://www.cfb.ie/fishing_in_ireland/CatchandRelease.htm and a question answered from Michigan DNR http://midnr.custhelp.com/cgi-bin/MiDNR.cfg/php/enduser/std_adp.php?p_sid=jDDHvB5i&p_lva=&p_faqid=1321&p_created=1026780064&p_sp=cF9zcmNoPTEmcF9ncmlkc29ydD0mcF9yb3dfY250PTMmcF9zZWFyY2hfdGV4dD1jYXRjaCBhbmQgcmVsZWFzZSZwX3Byb2RfbHZsMT0yJnBfcHJvZF9sdmwyPX5hbnl_JnBfcGFnZT0x&p_li=
We have tried it, but it's very hard to keep track of it (especially with the 2 boats, etc.) I've even made a laminated page to tally the fish on the boat.
