RE: fishing trip to Rhode Island
Many of the charter/party boats operate out of the Pt. Judith (Natrragansett RI) area, which is about 30 miles south of the airport. I think a rental car would be better, especially if the charter starts at some ungodly hour of the morning.
I happen to have a brochure from a party boat company that does 1-2 day tuna trips, night bass trips, etc. ... I would be glad to send them to you if you send me a private E-mail with an address.
The potential problem with tuna is that you usually have to charter or reserve well in advance (with a $deposit), and who knows what the weather will be like that day. To charter an individual boat that carries 4-6 passengers, you are probably talking at least $600 for the day, which is impractical for an individual (at least for me). Tuna fishing was very good in the area last year, so I would anticipate things filling up fast this year. I don't have any specific recommendations for boats/captains, but I'll be glad to do this:
1) Send a tourist map of RI
2) Send the brochure I have from the party boat co.
3) Photocopy the local yellow pages with charter fishing info.
