In April is all about watching the weather and having "Plan B" ready to execute." Snow storms/blizzards are not uncommon on the western slope or the front range in April/May.
I went to HS in Loveland back in the 70s. Many weekend dashes to the I-70W resorts for a day of skiing. Back then Estes Park was pretty much closed in the winter, nothing was open, no fast food, just the locals left to winter it out. Lake Eldora was the closest ski slop from where we lived, pretty tame compared to the others but still a fun time.
I want to drive the western segment of U.S. Route 2 one summer West to East.
