Don’t think I mentioned it here, but last month’s visit to Biscayne was my 394th (of 417) national park unit. I’ve now completed all 378 park units in the Contiguous US (plus those in Puerto Rico, Virgin Islands, Guam, and Hawaii). It’ll take me three summer trips to hit all of the remote Alaskan parks and the one in American Samoa, but holy cow, I’m actually getting close to finishing this 15-year-long quest!
